Answer the question based on the given passage

Management is a set of processes that can keep a complicated system of

people and technology running smoothly. The most important aspects of

management include planning, budgeting, organising, staffing, controlling,

and problem-solving. Leadership is a set of processes that creates

organisations in the first place or adapts them to significantly changing

circumstances. Leadership defines what the future should look like, aligns

people with that vision, and inspires them to make it happen despite the

obstacles. This distinction is absolutely crucial for our purposes here:

Successful transformation is 70 to 90 per cent leadership and only 10 to 30

percent management. Yet for historical reasons, many organisations today

don’t have much leadership. And almost everyone thinks about the problem

here as one of managing change. For most of this country, as we created

thousands and thousands of large organisations for the first time in human

history, we didn’t have enough good managers to keep all those bureaucracies

functioning. So many companies and universities developed management

programs and hundreds and thousands of people were encouraged to learn

management on the job. And they did. But, people were taught little about

leadership. To some degree, management was emphasised because it’s easier

to teach than leadership. But even more so, management was the main item

on the twentieth-century agenda because that’s what was needed. For every

entrepreneur or business builder who was a leader, we needed hundreds of

managers to run their ever-growing enterprises. Unfortunately for us today,

this emphasis on management has often been institutionalised in corporate

cultures that discourage employees from learning how to lead. Ironically, past

success is usually the key ingredient in producing this outcome. The

syndrome, as I have observed it on many occasions, goes like this: success

creates some degree of marked dominance which in turn produces much

growth. After a while keeping the ever-larger organisation under control

becomes the primary challenge. So attention turns inward and managerial

competencies are nurtured. With a strong emphasis on management but not

leadership, bureaucracy and an inward focus takeover. But with continued

success, the result mostly of market dominance, the problem often goes

unaddressed and an unhealthy arrogance begins to evolve. All of these

characteristics then make any transformation effort much more difficult.

Arrogant managers can over-evaluate their current performance and

competitive position, listen poorly and learn slowly. Inwardly focused

employees can have difficulty seeing the very forces that present threats and

opportunities. Bureaucratic cultures can smother those who want to respond

to shifting conditions. And the lack of leadership leaves no force inside

these organisations to break out of the morass.

Q11. Why did companies and universities develop programmes to

prepare managers in such a large number?

a. (A) Companies and universities wanted to generate funds through these

programmes

b. (B) The large number of organisations were created as they needed

managers in good number

c. (C) Organizations did not want to spend their scarce resources in training

managers

d. (D) Organisations wanted to create communication network through trained

managers

Q12. How has the author defined management?

a. It is the process of adapting organisations to changing circumstances.

b. It is the system of aligning people with the direction it has taken.

c. It refers to creating a vision to help direct the change effectively.

d. Creating better performance through customer orientation.

Q13. What is the historical reason for many organisations not having

leadership?

a. A view that leaders are born, they are not made

b. Leaders lack managerial skills and organisations need managers

c. Leaders are weak in carrying out traditional functions of management

d. Leaders allow too much complacency in organisations

Q14. Which of the following characteristics help organisations in their

transformation efforts?

a. Emphasis on leadership but not management

b. A strong and dogmatic culture

c. Bureaucratic and inward looking approach

d. Failing to acknowledge the value of customers and shareholders

Q15. Which of the following is similar in meaning of the word

‘smother’ as used in the passage?

Quantitative Aptitude - Problems on Time and Work1. If A can do a piece of work in n days, then A’s 1 day work = 1/n2. If A’s 1 day’s work = 1/n, then A can finish the work in n days.Example: If A can do a piece of work in 4 days,then A’s 1 day’s work = 1/4. If A’s 1 day’s work = 1/5, then A can finish the work in 5 days

3. If A is thrice as good workman as B,then: Ratio of work done by A and B = 3:1. Ratio of time taken by A and B to finish a work = 1:3

4. Definition of Variation: The change in two different variables follow some definite rule. It said that the two variables vary directly or inversely. Its notation is X/Y = k, where k is called constant. This variation is called direct variation. XY = k. This variation is called inverse variation.

5. Some Pairs of Variables:1. Number of workers and their wages. If the number of workers increases, their total wages increase. If the number of days reduced, there will be less work. If the number of days is increased, there will be more work. Therefore, here we have direct proportion or direct variation.

2. Number workers and days required to do a certain work is an example of inverse variation. If more men are employed, they will require fewer days and if there are less number of workers, more days are required.

3. There is an inverse proportion between the daily hours of a work and the days required. If the number of hours is increased, less number of days are required and if the number of hours is reduced, more days are required.

6. Some Important Tips:More Men - Less Days and Conversely More Day - Less Men.More Men - More Work and Conversely More Work - More Men.More Days - More Work and Conversely More Work - More Days.Number of days required to complete the given work = Total work/One day’s work.

Since the total work is assumed to be one(unit), the number of days required to complete the given work would be the reciprocal of one day’s work. Sometimes, the problems on time and work can be solved using the proportional rule ((man*days*hours)/work) in another situation.

7. If men is fixed,work is proportional to time. If work is fixed, then time is inversely proportional to men therefore, (M1*T1/W1) = (M2*T2/W2)

Problems on Time and Work1) If 9 men working 6 hours a day can do a work in 88 days. Then 6 men working 8 hours a day can do it in how many days?Solution: From the above formula i.e (m1*t1/w1) = (m2*t2/w2)so (9*6*88/1) = (6*8*d/1)on solving, d = 99 days.

2) If 34 men completed 2/5th of a work in 8 days working 9 hours a day. How many more man should be engaged to finish the rest of the work in 6 days working 9 hours a day?

Solution: From the above formula i.e (m1*t1/w1) = (m2*t2/w2)so, (34*8*9/(2/5)) = (x*6*9/(3/5))so x = 136 mennumber of men to be added to finish the work = 136-34 = 102 men

3) If 5 women or 8 girls can do a work in 84 days. In how many days can 10 women and 5 girls can do the same work?

Solution: Given that 5 women is equal to 8 girls to complete a workso, 10 women = 16 girls.Therefore 10women +5girls = 16girls+5girls = 21 girls.8 girls can do a work in 84 daysthen 21 girls ————— ?Answer = (8*84/21) = 32 days. Therefore 10 women and 5 girls can a work in 32 days

4) Worker A takes 8 hours to do a job. Worker B takes 10hours to do the same job. How long it take both A & B, working together but independently, to do the same job?

Solution: A’s one hour work = 1/8.B’s one hour work = 1/10(A+B)’s one hour work = 1/8+1/10 = 9/40Both A & B can finish the work in 40/9 days

5) A can finish a work in 18 days and B can do the same work in half the time taken by A. Then, working together, what part of the same work they can finish in

a day?

Solution:Given that B alone can complete the same work in days = half the timetaken by A = 9daysA’s one day work = 1/18B’s one day work = 1/9(A+B)’s one day work = 1/18+1/9 = 1/6

6) A is twice as good a workman as B and together they finish a piece of work in 18 days.In how many days will A alone finish the work.

Solution: if A takes x days to do a work thenB takes 2x days to do the same work= > 1/x+1/2x = 1/18= > 3/2x = 1/18= > x = 27 days.Hence, A alone can finish the work in 27 days.

7) A can do a certain work in 12 days. B is 60% more efficient than A. How many days does B alone take to do the same job?

Solution: Ratio of time taken by A & B = 160:100 = 8:5Suppose B alone takes x days to do the job.Then, 8:5::12:x= > 8x = 5*12= > x = 15/2 days.

8) A can do a piece of work n 7 days of 9 hours each and B alone can do it in 6 days of 7 hours each. How long will they take to do it working together 8 2/5 hours a day?

Solution: A can complete the work in (7*9) = 63 daysB can complete the work in (6*7) = 42 days= > A’s one hour’s work = 1/63 andB’s one hour work = 1/42(A+B)’s one hour work = 1/63+1/42 = 5/126Therefore, Both can finish the work in 126/5 hours.Number of days of 8 2/5 hours each = (126*5/(5*42)) = 3 days

9) A takes twice as much time as B or thrice as much time to finish a piece of work. Working together they can finish the work in 2 days. B can do the work alone in ?

Solution: Suppose A,B and C take x,x/2 and x/3 hours respectively finish thework then 1/x+2/x+3/x = 1/2= > 6/x = 1/2= >x = 12So, B takes 6 hours to finish the work.

10) X can do ¼ of a work in 10 days, Y can do 40% of work in 40 days and Z can do 1/3 of work in 13 days. Who will complete the work first?

Solution: Whole work will be done by X in 10*4 = 40 days.Whole work will be done by Y in (40*100/40) = 100 days.

Whole work will be done by Z in (13*3) = 39 daysTherefore,Z will complete the work first.Complex Problems on Time and Work

1) A and B undertake to do a piece of workfor Rs 600. A alone can do it in 6 days while B alone can do it in 8 days. With the help of C, they can finish it in 3 days, Find the share of each?

Solution:C’s one day’s work = (1/3)-(1/6+1/8) = 1/24Therefore, A:B:C = Ratio of their one day’s work = 1/6:1/8:1/24 = 4:3:1A’s share = Rs (600*4/8) = 300B’s share = Rs (600*3/8) = 225C’s share = Rs[600-(300+225)] = Rs 75

2) A can do a piece of work in 80 days. He works at it for 10 days & then B alone finishes the remaining work in 42 days. In how much time will A and B, working together, finish the work?

Solution: Work done by A in 10 days = 10/80 = 1/8Remaining work = (1-(1/8)) = 7/8Now, work will be done by B in 42 days.Whole work will be done by B in (42*8/7) = 48 daysTherefore, A’s one day’s work = 1/80B’s one day’s work = 1/48(A+B)’s one day’s work = 1/80+1/48 = 8/240 = 1/30Hence, both will finish the work in 30 days.

3) P,Q and R are three typists who working simultaneously can type 216 pages in 4 hours In one hour, R can type as many pages more than Q as Q can type more than P. During a period of five hours, R can type as many pages as P can during seven hours. How many pages does each of them type per hour?

Solution: Let the number of pages typed in one hour by P, Q and R be x,y and z respectively. Thenx+y+z = 216/4 = 54 ————— 1z-y = y-x = > 2y = x+z ———–— 25z = 7x = > x = 5x/7 ————— 3Solving 1,2 and 3 we get x = 15,y = 18, and z = 21

4) Ronald and Elan are working on an assignment. Ronald takes 6 hours to type 32 pages on a computer, while Elan takes 5 hours to type 40 pages. How much time will they take, working together on two different computers to type an assignment of 110 pages?

Solution: Number of pages typed by Ronald in one hour = 32/6 = 16/3Number of pages typed by Elan in one hour = 40/5 = 8Number of pages typed by both in one hour = ((16/3)+8) = 40/3Time taken by both to type 110 pages = 110*3/40 = 8 hours.

5) Two workers A and B are engaged to do a work. A working alone takes 8 hours more to complete the job than if both working together. If B worked alone, he would need 4 1/2 hours more to compete the job than they both working together. What time would they take to do the work together.

Solution: (1/(x+8))+(1/(x+(9/2))) = 1/x= >(1/(x+8))+(2/(2x+9)) = 1/x= > x(4x+25) = (x+8)(2x+9)= > 2×2 = 72= > x2 = 36= > x = 6Therefore, A and B together can do the work in 6 days.

6) A and B can do a work in12 days, B and C in 15 days, C and A in 20 days. If A,B and C work together, they will complete the work in how many days?

Solution: (A+B)’s one day’s work = 1/12;(B+C)’s one day’s work = 1/15;(A+C)’s one day’s work = 1/20;Adding we get 2(A+B+C)’s one day’s work = 1/12+1/15+1/20 = 12/60 = 1/5(A+B+C)’s one day work = 1/10So, A,B,and C together can complete the work in 10 days.

7) A and B can do a work in 8 days, B and C can do the same wor in 12 days. A,B and C together can finish it in 6 days. A and C together will do it in how many days?

Solution: (A+B+C)’s one day’s work = 1/6;(A+B)’s one day’s work = 1/8;(B+C)’s one day’s work = 1/12;(A+C)’s one day’s work = 2(A+B+C)’s one day’s work-((A+B)’s one daywork+(B+C)’s one day work)= (2/6)-(1/8+1/12)= (1/3)- (5/24)= 3/24= 1/8So, A and C together will do the work in 8 days.

8) A can do a certain work in the same time in which B and C together can do it. If A and B together could do it in 10 days and C alone in 50 days, then B alone could do it in how many days?

Solution: (A+B)’s one day’s work = 1/10;C’s one day’s work = 1/50(A+B+C)’s one day’s work = (1/10+1/50) = 6/50 = 3/25Also, A’s one day’s work = (B+C)’s one day’s workFrom i and ii ,we get :2*(A’s one day’s work) = 3/25= > A’s one day’s work = 3/50B’s one day’s work = (1/10-3/50)= 2/50= 1/25B alone could complete the work in 25 days.

9) A is thrice as good a workman as B and therefore is able to finish a job in 60 days less than B. Working together, they can do it in:

Solution: Ratio of times taken by A and B = 1:3.If difference of time is 2 days , B takes 3 daysIf difference of time is 60 days, B takes (3*60/2) = 90 days

So, A takes 30 days to do the work = 1/90A’s one day’s work = 1/30;B’s one day’s work = 1/90;(A+B)’s one day’s work = 1/30+1/90 = 4/90 = 2/45Therefore, A & B together can do the work in 45/2days10) A can do a piece of work in 80 days. He works at it for 10 days and then B alone finishes the remaining work in 42 days. In how much time will A & B, working together, finish the work?

Solution: Work Done by A n 10 days = 10/80 = 1/8Remaining work = 1-1/8 = 7/8Now 7/8 work is done by B in 42 daysWhole work will be done by B in 42*8/7 = 48 days= > A’s one day’s work = 1/80 andB’s one day’s work = 1/48(A+B)’s one day’s work = 1/80+1/48 = 8/240 = 1/30Hence both will finish the work in 30 days.

11) 45 men can complete a work in 16 days. Six days after they started working, so more men joined them. How many days will they now take to complete the remaining work?

Solution: M1*D1/W1 = M2*D2/W2= >45*6/(6/16) = 75*x/(1-(6/16))= > x = 6 days

12) A is 50% as efficient as B. C does half the work done by A & B together. If C alone does the work n 40 days, then A,B and C together can do the work in:

Solution: A’s one day’s work:B’s one days work = 150:100 = 3:2Let A’s & B’s one day’s work be 3x and 2x days respectively.Then C’s one day’s work = 5x/2= > 5x/2 = 1/40= > x = ((1/40)*(2/5)) = 1/100A’s one day’s work = 3/100B’s one day’s work = 1/50C’s one day’s work = 1/40So, A,B and C can do the work in 13 1/3 days.

13) A can finish a work in 18 days and B can do the same work in 15 days. B worked for 10 days and left the job. In how many days A alone can finish the remaining work?

Solution: B’s 10 day’s work = 10/15 = 2/3Remaining work = (1-(2/3)) = 1/3Now, 1/18 work is done by A in 1 day.Therefore 1/3 work is done by A in 18*(1/3) = 6 days.

14) A can finish a work in 24 days, B n 9 days and C in 12 days. B & C start the work but are forced to leave after 3 days. The remaining work done by A in:

Solution: (B+C)’s one day’s work = 1/9+1/12 = 7/36Work done by B & C in 3 days = 3*7/36 = 7/12Remaining work = 1-(7/12) = 5/12

Now , 1/24 work is done by A in 1 day.So, 5/12 work is done by A in 24*5/12 = 10 days

15) X and Y can do a piece of work n 20 days and 12 days respectively. X started the work alone and then after 4 days Y joined him till the completion of work. How long did the work last?

Solution: work done by X in 4 days = 4/20 = 1/5Remaining work = 1-1/5 = 4/5(X+Y)’s one day’s work = 1/20+1/12 = 8/60 = 2/15Now, 2/15 work is done by X and Y in one day.So, 4/5 work will be done by X and Y in 15/2*4/5 = 6 daysHence Total time taken = (6+4) days = 10 days

16) A does 4/5 of work in 20 days. He then calls in B and they together finish the remaining work in 3 days. How long B alone would take to do the whole work?

Solution: Whole work is done by A in 20*5/4 = 25 daysNow, (1-(4/5)) i.e 1/5 work is done by A & B in days.Whole work will be done by A & B in 3*5 = 15 days= >B’s one day’s work = 1/15-1/25 = 4/150 = 2/75So, B alone would do the work in 75/2 = 37 ½ days.

17) A and B can do a piece of work in 45 days and 40 days respectively. They began to do the work together but A leaves after some days and then B completed the remaining work n 23 days. The number of days after which A left the work was

Solution: (A+B)’s one day’s work = 1/45+1/40 = 17/360Work done by B in 23 days = 23/40Remaining work = 1-(23/40) = 17/40Now, 17/360 work was done by (A+B) in 1 day.17/40 work was done by (A+B) in (1*(360/17)*(17/40)) = 9 daysSo, A left after 9 days.

18) A can do a piece of work in 10 days, B in 15 days. They work for 5 days. The rest of work finished by C in 2 days. If they get Rs 1500 for the whole work, the daily wages of B and C are:

Solution: Part of work done by A = 5/10 = 1/2Part of work done by B = 1/3Part of work done by C = (1-(1/2+1/3)) = 1/6A’s share: B’s share: C’s share = 1/2:1/3:1/6 = 3:2:1A’s share = (3/6)*1500 = 750B’s share = (2/6)*1500 = 500C’s share = (1/6)*1500 = 250A’s daily wages = 750/5 = 150/-B’s daily wages = 500/5 = 100/-C’s daily wages = 250/2 = 125/-Daily wages of B & C = 100+125 = 225/-

19) A alone can complete a work in 16 days and B alone can complete the same in 12 days. Starting with A, they work on alternate days. The total work will be completed in how many days?

(a) 12 days (b) 13 days (c) 13 5/7 days (d)13 ¾ days

Solution: (A+B)’s 2 days work = 1/16 + 1/12 = 7/48work done in 6 pairs of days = (7/48) * 6 = 7/8remaining work = 1- 7/8 = 1/8work done by A on 13th day = 1/16remaining work = 1/8 – 1/16 = 1/16on 14th day, it is B’s turn1/12 work is done by B in 1 day.1/16 work is done by B in ¾ day.Total time taken = 13 ¾ days.So, Answer is: D

20) A,B and C can do a piece of work in 20,30 and 60 days respectively. In how many days can A do the work if he is assisted by B and C on every third day?

Solution: A’s two day’s work = 2/20 = 1/10(A+B+C)’s one day’s work = 1/20+1/30+1/60 = 6/60 = 1/10Work done in 3 days = (1/10+1/10) = 1/5Now, 1/5 work is done in 3 daysTherefore, Whole work will be done in (3*5) = 15 days.

21) Seven men can complete a work in 12 days. They started the work and after 5 days, two men left. In how many days will the work be completed by the remaining men?

(A) 5 (B) 6 (C ) 7 (D) 8 (E) none

Solution: 7*12 men complete the work in 1 day.Therefore, 1 man’s 1 day’s work = 1/847 men’s 5 days work = 5/12= >remaining work = 1-5/12 = 7/125 men’s 1 day’s work = 5/845/84 work is don by them in 1 day7/12 work is done by them in ((84/5) * (7/12)) = 49/5 days = 9 4/5 days.Ans: E

22) 12 men complete a work in 9 days. After they have worked for 6 days, 6 more men joined them. How many days will they take to complete the remaining work?

(a) 2 days (b) 3 days (c) 4 days (d) 5days

Solution: 1 man’s 1 day work = 1/10812 men’s 6 days work = 6/9 = 2/3remaining work = 1 – 2/3 = 1/318 men’s 1 days work = 18/108 = 1/61/6 work is done by them in 1 daytherefore, 1/3 work is done by them in 6/3 = 2 days.Ans : A

23) A man, a woman and a boy can complete a job in 3,4 and 12 days respectively. How many boys must assist 1 man and 1 woman to complete the job in ¼ of a day?

(a). 1 (b). 4 (c). 19 (d). 41

Solution: (1 man + 1 woman)’s 1 days work = 1/3+1/4 = 7/12Work done by 1 man and 1 women n 1/4 day = ((7/12)*(1/4)) = 7/48Remaining work = 1- 7/48 = 41/48Work done by 1 boy in ¼ day = ((1/12)*(1/4)) = 1/48Therefore, Number of boys required = ((41/48)*48) = 41 daysSo,Answer: D

24) 12 men can complete a piece of work in 4 days, while 15 women can complete the same work in 4 days. 6 men start working on the job and after working for 2 days, all of them stopped working. How many women should be put on the job to complete the remaining work, if it is to be completed in 3 days.

(A) 15 (B) 18 (C) 22 (D) data inadequate

Solution: one man’s one day’s work = 1/48one woman’s one day’s work = 1/606 men’s 2 day’s work = ((6/48)*2) = ¼Remaining work = 3/4Now, 1/60 work s done in 1 day by 1 woman.So, ¾ work will be done in 3 days by (60*(3/4)*(1/3)) = 15 woman.So, Answer: A

25) Twelve children take sixteen days to complete a work which can be completed by 8 adults in 12 days. Sixteen adults left and four children joined them. How many days will they take to complete the remaining work?

(A) 3 (B) 4 ( C) 6 (D) 8

Solution: one child’s one day work = 1/192;one adult’s one day’s work = 1/96;work done in 3 days = ((1/96)*16*3) = 1/2Remaining work = 1 – ½ = 1/2(6 adults+ 4 children)’s 1 day’s work = 6/96+4/192 = 1/121/12 work is done by them in 1 day.½ work is done by them 12*(1/2) = 6 daysSo, Answer = C

26) Sixteen men can complete a work in twelve days. Twenty four children can complete the same work in 18 days. 12 men and 8 children started working and after eight days three more children joined them. How many days will they now take to complete the remaining work?

(A) 2 days (B) 4 days ( C) 6 days (D) 8 days

Solution: one man’s one day’s work = 1/192one child’s one day’s work = 1/432Work done in 8 days = 8*(12/192+ 8/432) = 8*(1/16+1/54) = 35/54Remaining work = 1 -35/54 = 19/54(12 men+11 children)’s 1 day’s work = 12/192 + 11/432 = 19/216Now, 19/216 work is done by them in 1 day.Therefore, 19/54 work will be done by them in ((216/19)*(19/54)) = 4 daysSo,Answer: B

27) Twenty-four men can complete a work in 16 days. Thirty- two women can complete the same work in twenty-four days. Sixteen men and sixteen women started working and worked for 12 days. How many more men are to be added to complete the remaining work in 2 days?

(A) 16 men (B) 24 men ( C) 36 men (D) 48 men

Solution: one man’s one day’s work = 1/384one woman’s one day’s work = 1/768Work done in 12 days = 12*( 16/384 + 16/768) = 12*(3/48) = 3/4Remaining work = 1 – ¾ = 1/4(16 men+16 women)’s two day’s work = 12*( 16/384+16/768) = 2/16 = 1/8Remaining work = 1/4-1/8 = 1/81/384 work is done n 1 day by 1 man.Therefore, 1/8 work will be done in 2 days in 384*(1/8)*(1/2) = 24men

28) 4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it?

(A) 35 days (B) 40 days ( C) 45 days (D) 50 days

Solution: Let 1 man’s 1 day’s work = x days and1 woman’s 1 day’s work = yThen, 4x+6y = 1/8 and 3x+7y = 1/10.Solving these two equations, we get: x = 11/400 and y = 1/400Therefore, 1 woman’s 1 day’s work = 1/400= > 10 women will complete the work in 40 days.Answer: B

29) One man, 3 women and 4 boys can do a piece of work in 96 hours, 2 men and 8 boys can do it in 80 hours, 2 men & 3 women can do it in 120 hours. 5 Men & 12 boys can do it in how many hours?

(A) 39 1/11 hrs (B) 42 7/11 hrs ( C) 43 7/11 days (D) 44hrs

Solution: Let 1 man’s 1 hour’s work = x1 woman’s 1 hour’s work = y1 boy’s 1 hour’s work = zThen, x+3y+4z = 1/96 ———– (1)2x+8z = 1/80 ———- (2)adding (2) & (3) and subtracting (1)3x+4z = 1/96 ———(4)From (2) and (4), we get x = 1/480Substituting, we get : y = 1/720 and z = 1/960(5 men+ 12 boy)’s 1 hour’s work = 5/480+12/960 = 1/96 + 1/80 = 11/480Therefore, 5 men and 12 boys can do the work in 480/11 or 43 7/11hours.So, Answer: C

Passage(Questions From 17-21): A spate of soul-searching is guaranteed by two major anniversaries that loom this year: the abolition of the slave trade in the British empire in 1807, and the Act of Union of England and Scotland in 1707. Both will feed into Britain's nagging sense of self-doubt: who are we? As the debates around integrated and multi-culturalism show no sign of flagging, both anniversaries will be mind for their contemporary relevance.

Television programmes, books, ceremonies, conferences, and newspaper supplements have been in the planning for months.

Some might regard this self-referentialism as tedious; they might advocate an apology for the slave trade and let's be done with 2007's anniversaries. But our reckoning with British history has been so limited that these two anniversaries provide us with a good opportunity for an overdue reality check.

Any chance of reinventing a plausible national identity now (as many are keen to do) is only possible if we develop a much better understanding of how our nation behaved in the past and how nationalisms (English, Scottish, and British) were elaborately created over the past few hundred years — and how incomplete and fragile that process always was.

The coincidence of these two anniversaries is fortuitous. The abolition of the slave trade is a painful reminder of British imperial history, which we have, incredible, managed to largely forget. Who remembers the Bengal famine or Hola camp, the empire's opium trade with China or our invention of concentration camps in the Boer war? We too easily overlook how empire was a linchpin to British national identity, vital to welding Scotland and England together. Indeed, historian Linda Colley suggests three ingredients for British identity: “Great Britain is an invented nation that was not founded on the suppression of older loyalties so much as superimposed on them, and that was heavily dependent for its raison d'etre on a broadly Protestant culture, on the treat and tonic of recurrent war, especially war with France, and on the triumphs, profits and Otherness represented by a massive overseas empire.”

These three props for Britishness have collapsed: Protestant Christianity has declined sharply, war with France is the pastime only of a few drunken football fans, and the empire is no more. No wonder Britishness is no the decline; over the past couple of decades, people have become increasingly likely to define themselves in polls as English or Scottish rather than British.

This is the social trend in defining identity that politicians such as Gordon Brown watch closely. Could this re-emergence of the older loyalties to which Ms Colley refers have political consequences? Could the Scottish National Party translate that into significant electoral gains in the Scottish elections only a few days after the official commemoration of the Act of Union in May?

It's not just the Scots who could decide they've had enough of the English — the feeling could become mutual. The grumbles are getting louder about Scottish MPs who vote on legislation affecting the English and the disproportionate amount of public spending swallowed up by the Scots.

Mr Brown clearly has a vested interest in stilling such complaints. He's been at the forefront of an establishment attempt to redefine Britishness on the grounds of “common values” such as fair play and tolerance.

Who is going to define Englishness? Julian Baggini has a stab at it in a book to be published in March, Welcome to Every town: A Journey into the English Mind. He spent six months living in Rotherham to get beyond the metropolitan, liberal elite's perceptions of Englishness and establish what most people (that is, the white working class) understand by their Englishness.

Parochial, tightly knit, focused on family and local communities; nostalgic, fearful of the future and insecure; a dogged belief in common sense: these are his conclusions. Mr Baggini confesses to feeling that his six months in Rotherham was like visiting a foreign country, and no doubt many of the people he met would regard six months in London as profoundly alienating. How do you weld national identities out of global metropolises disconnected from hinterland? Englishness is riven with huge regional and class divides. The stakes are high — for example, a rising British National Party vote, a fear of asylum, and hostility to Islam. The anniversary of the Act of union will provide a stage for all this to be played out. It's just as painful a commemoration for the English as for the Scottish. It required one nation to lose its sovereignty and the other its identity.

17. According to the passage, the two major anniversaries will1) give an impetus to the questioning of British national identity.2) set the Britons thinking who they really are.3) be just another occasion to raise the issue of British national identity.4) be just another occasion to give rise to a debate on multiculturalism.5) not be celebrated because of the shame attached with slave trade.

18. According to Linda Colley, Great Britain owes its nation-state concept to1) ceding of its territory by Scotland to England.2) a shared relation of race, religion and economy.3) what can today be seen as a concept of free trade area.4) the perpetuation of slave trade.5) commonality of interest between its constituents.

19. Going by the passage, which of the following may instill a sense of national identity among the Britons?1) The return of Catholics to the Protestant fold2) Britain going to war with Germany3) Britain going to war as an Allied force4) Regular football matches between British and French clubs5) Any of the above

20. According to the facts stated in the passage, if England and Scotland decide to split,1) it is the former that stands to gain.2) it is the latter that stands to gain.3) it will be a win-win situation.4) it will be a lose-lose situation.5) both the parties will lose their face but gain materially

21. According to the passage, the post-modern mind views imperialism as1) something that was necessary in the context of the times.2) a thing of the past which need not be mentioned further.

3) a blot on the history of mankind.4) the white man's burden.5) a concept relevant even in the present times, given the inability of the developing countries to catch up with the West.

Answer the question based on the given passage

Management is a set of processes that can keep a complicated system of people and technology running smoothly. The most important aspects of management include planning, budgeting, organising, staffing, controlling, and problem-solving. Leadership is a set of processes that creates organisations in the first place or adapts them to significantly changing circumstances. Leadership defines what the future should look like, aligns people with that vision, and inspires them to make it happen despite the obstacles. This distinction is absolutely crucial for our purposes here: Successful transformation is 70 to 90 per cent leadership and only 10 to 30 percent management. Yet for historical reasons, many organisations today don't have much leadership. And almost everyone thinks about the problem here as one of managing change. For most of this country, as we created thousands and thousands of large organisations for the first time in human history, we didn't have enough good managers to keep all those bureaucracies functioning. So many companies and universities developed management programs and hundreds and thousands of people were encouraged to learn management on the job. And they did. But, people were taught little about leadership. To some degree, management was emphasised because it's easier to teach than leadership. But even more so, management was the main item on the twentieth-century agenda because that's what was needed. For every entrepreneur or business builder who was a leader, we needed hundreds of managers to run their ever-growing enterprises. Unfortunately for us today, this emphasis on management has often been institutionalised in corporate cultures that discourage employees from learning how to lead. Ironically, past success is usually the key ingredient in producing this outcome. The syndrome, as I have observed it on many occasions, goes like this: success creates some degree of marked dominance which in turn produces much growth. After a while keeping the ever-larger organisation under control becomes the primary challenge. So attention turns inward and managerial competencies are nurtured. With a strong emphasis on management but not leadership, bureaucracy and an inward focus takeover. But with continued success, the result mostly of market dominance, the problem often goes unaddressed and an unhealthy arrogance begins to evolve. All of these characteristics then make any transformation effort much more difficult. Arrogant managers can over-evaluate their current performance and competitive position, listen poorly and learn slowly. Inwardly focused employees can have difficulty seeing the very forces that present threats and opportunities. Bureaucratic cultures can smother those who want to respond to shifting conditions. And the lack of leadership leaves no force inside these organisations to break out of the morass.

Q11. Why did companies and universities develop programmes to prepare managers in such a large number?

a. (A) Companies and universities wanted to generate funds through these programmesb. (B) The large number of organisations were created as they needed managers in good numberc. (C) Organisations did not want to spend their scarce resources in training managersd. (D) Organisations wanted to create communication network through trained managers

Q12. How has the author defined management?

a. It is the process of adapting organisations to changing circumstances.b. It is the system of aligning people with the direction it has taken.c. It refers to creating a vision to help direct the change effectively.d. Creating better performance through customer orientation.

Q13. What is the historical reason for many organisations not having leadership?

a. A view that leaders are born, they are not madeb. Leaders lack managerial skills and organisations need managersc. Leaders are weak in carrying out traditional functions of managementd. Leaders allow too much complacency in organisations

Q14. Which of the following characteristics help organisations in their transformation efforts?

a. Emphasis on leadership but not managementb. A strong and dogmatic culturec. Bureaucratic and inward looking approach d. Failing to acknowledge the value of customers and shareholders

Q15. Which of the following is similar in meaning of the word 'smother' as used in the passage?

Passage(Questions From 17-21):A spate of soul-searching is guaranteed by two major anniversaries that loom this year: the abolition of the slave trade in the British empire in 1807, and the Act of Union of England and Scotland in 1707. Both will feed into Britain's nagging sense of self-doubt: who are we? As the debates around integrated and multi-culturalism show no sign of flagging, both anniversaries will be mind for their contemporary relevance.

Television programmes, books, ceremonies, conferences, and newspaper supplements have been in the planning for months.

Some might regard this self-referentialism as tedious; they might advocate an apology for the slave trade and let's be done with 2007's anniversaries. But our reckoning with British history has been so limited that these two anniversaries provide us with a good opportunity for an overdue reality check.

Any chance of reinventing a plausible national identity now (as many are keen to do) is only possible if we develop a much better understanding of how our nation behaved in the past and how nationalisms (English, Scottish, and British) were elaborately created over the past few hundred years — and how incomplete and fragile that process always was.The coincidence of these two anniversaries is fortuitous. The abolition of the slave trade is a painful reminder of British imperial history, which we have, incredible, managed to largely forget. Who remembers the Bengal famine or Hola camp, the empire's opium trade with China or our invention of concentration camps in the Boer war? We too easily overlook how empire was a linchpin to British national identity, vital to welding Scotland and England together. Indeed, historian Linda Colley suggests three ingredients for British identity: “Great Britain is an invented nation that was not founded on the suppression of older loyalties so much as superimposed on them, and that was heavily dependent for its raison d'etre on a broadly Protestant culture, on the treat and tonic of recurrent war, especially war with France, and on the triumphs, profits and Otherness represented by a massive overseas empire.”

These three props for Britishness have collapsed: Protestant Christianity has declined sharply, war with France is the pastime only of a few drunken football fans, and the empire is no more. No wonder Britishness is no the decline; over the past couple of decades, people have become increasingly likely to define themselves in polls as English or Scottish rather than British.

This is the social trend in defining identity that politicians such as Gordon Brown watch closely. Could this re-emergence of the older loyalties to which Ms Colley refers have political consequences? Could the Scottish National Party translate that into significant electoral gains in the Scottish elections only a few days after the official commemoration of the Act of Union in May?

It's not just the Scots who could decide they've had enough of the English — the feeling could become mutual. The grumbles are getting louder about Scottish MPs who vote on legislation affecting the English and the disproportionate amount of public spending swallowed up by the Scots.

Mr Brown clearly has a vested interest in stilling such complaints. He's been at the forefront of an establishment attempt to redefine Britishness on the grounds of “common values” such as fair play and tolerance.

Who is going to define Englishness? Julian Baggini has a stab at it in a book to be published in March, Welcome to Every town: A Journey into the English Mind. He spent six months living in Rotherham to get beyond the metropolitan, liberal elite's perceptions of Englishness and establish what most people (that is, the white working class) understand by their Englishness.

Parochial, tightly knit, focused on family and local communities; nostalgic, fearful of the future and insecure; a dogged belief in common sense: these are his conclusions. Mr Baggini confesses to feeling that his six months in Rotherham was like visiting a foreign country, and no doubt many of the people he met would regard six months in London as profoundly

alienating. How do you weld national identities out of global metropolises disconnected from hinterland? Englishness is riven with huge regional and class divides. The stakes are high — for example, a rising British National Party vote, a fear of asylum, and hostility to Islam. The anniversary of the Act of union will provide a stage for all this to be played out. It's just as painful a commemoration for the English as for the Scottish. It required one nation to lose its sovereignty and the other its identity.

17. According to the passage, the two major anniversaries will1) give an impetus to the questioning of British national identity.2) set the Britons thinking who they really are.3) be just another occasion to raise the issue of British national identity.4) be just another occasion to give rise to a debate on multiculturalism.5) not be celebrated because of the shame attached with slave trade.

18. According to Linda Colley, Great Britain owes its nation-state concept to1) ceding of its territory by Scotland to England.2) a shared relation of race, religion and economy.3) what can today be seen as a concept of free trade area.4) the perpetuation of slave trade.5) commonality of interest between its constituents.

19. Going by the passage, which of the following may instill a sense of national identity among the Britons?1) The return of Catholics to the Protestant fold2) Britain going to war with Germany3) Britain going to war as an Allied force4) Regular football matches between British and French clubs5) Any of the above

20. According to the facts stated in the passage, if England and Scotland decide to split,1) it is the former that stands to gain.2) it is the latter that stands to gain.3) it will be a win-win situation.4) it will be a lose-lose situation.5) both the parties will lose their face but gain materially

21. According to the passage, the post-modern mind views imperialism as1) something that was necessary in the context of the times.2) a thing of the past which need not be mentioned further.3) a blot on the history of mankind.4) the white man's burden.5) a concept relevant even in the present times, given the inability of the developing countries to catch up with the West.

After one month, the routes of the northern and southern groups converge for a brief time and at that point theknights can, if they wish, rearrange their traveling parties before continuing, again in two parties along separatenorthern and southern routes. Throughout the entire trip, the composition of traveling parties must be in accord with the following conditions

P and R are deadly enemies and, although they may meet briefly, can never travel together. p must travel in the same party with S Q can't travel by the southern route U can't change routes

11) If one of the two parties of knights consists of P and U and two other knights and travels by the southern route, the other members of this party besides P and U must bea) Q and Sb) Q and Tc) R and Sd) R and Te) S and TAns: e

PAPER : HCL Technical Placement Paper Pattern

Section 1:

In this section there are mainly questions based on C language like find the errors in the

program and what is the output of the following program.

some question i remember are

1) int i=10;

printf("%d %d %d",i++,i++,i--);

there is one or two more question on increment operator

2) Two question on redirection operator(>>)

3) int i=10;

if(1,i++,++i)

printf("The value for i is %d",i);

4) one question on structure and u have to fine the error in the syntax

5) int a=10,b=33;

a=a^b;

b=a^b;

a=a^b;

printf("%d %d", a,b);

6) int *a;

int (*b)();

printf("%d %d",sizeof(a),sizeof(b);

7) # define SQR(a) (a*a)

void main()

{

printf("%d", SQR(5));

}

8) And in another question # define directive is declared in the main() function of

the program and u have to predict the output of the program.?

9) what is the time complexity of bubble sort (Ans: O(n^2))

10) What is the size of the address bus and data bus in 8086?

11) address of IVT in 8086?

Section II:

1) some 6 guys are there A,B,C,D,E,F(say) and u have to adjust in the row. and some

statements are there like A & D can't be adjacent E,A have one vacant area in between.. like

that and there are 5 questions are based on that?

2) this one is tricky .. there are two groups . one is many brothers can mary one sister of

other group. and second is many sister can mary one brother of other group and some

statements are there like V & U is father of S, X is the only grandmother of S ...like that.. And

there are 6 question based on that..

3) and rest of questions are purely aptitude & quant based. like there are two questions on

coding if MYSORE is code like MEMEME then how TAMILNADU is coded?

(2.1)Design a state-machine (or draw a state-diagram) to give an output '1' when the # of A's are even and # of B's are odd. The input is in the form of a serial-stream (one-bit per clock cycle). The inputs could be of the type A, B or C. At any given clock cycle, the output is a '1', provided the # of A's are even and # of B's are odd. At any given clock cycle, the output is a '0', if the above condition is not satisfied.

(2.2). To detect the sequence "abca" when the inputs can be a b c d.
