You have 8 routes to go from your home to office. How many choices do you have to go and return (you don’t use same route while returning)?

8 * 7 =56 (because you don’t use same route

while returning, so choices are not 8 but 7).


You have 8 routes to go from your home to office. How many choices do you have to go and return (you use same route while returning)?

8 answer (because you don’t have choice while

returning).


How many telephone connections can be alloted from 8 numbers – from 0 to 9?

You can use a number again and again – for example a number can be 11111111.

Thus you have 10 choices for each of the 8 digits.

Thus 10^8 is the answer.


3 persons have 8 seats for them. In how many ways can they occupy these?

8p3 (because order is important here, so use permutation).


How many 4 digit numbers greater than 7000 can be formed out of 3,4,7,8,9?

You have 3 choices for first digit (7,8,9) You have now (5-1) = 4 choices for 2nd

digit, you have 3 choices for 3rd digit, you have 2 choices for 4th digit.

Thus : 3*4*3*2 = 72 answer.


In how many ways can we arrange 5 books of OB, 3 of Mgmt and 3 of Law, if books of one subject are always together?

There are 3 subjects, so we have 3!. Books of one subject can be

interchanged easily. Thus we have 5!*3!*3!

=3!*5!*3!*3! =25920 Answer.


In how many ways can we set 10 examination papers so that the best and the worst paper never come together?

1. We have total 10! 2. But best and worst cannot come

together, let us treat them as one and find the cases when they come together. Thus we have (10-1)!*2

3. Remove step 2 from step 1. 4. Answer: 10! – (9!*2)=2903040


We organise a group discussion at AFTERSCHOOOL, where 15 students participate. Two particular students always sit together. In how many ways can they sit for GD?

Two students are always together, so let us treat them as one. We have 14 students now.

(N-1)!. Thus 13 factorial. However, 2 students can exchange seats among themselves, so we have 13! * 2 answer.

=12454041600 ans.


How many 4 digit words can be made from Mathematics?

We have 11 digits. We have repeatition of A, T, M. Thus we have 8 digits. We have choices

like all different digits, or 2 common and 2 different digits or 2 pairs.

All different : 8p4 = 1680 1 pair and 3 different digits: 3p1 *7p2 =

126 *3! =756 2 pairs from 3 = 3p2 = 6 *3 = 18 Total =2454 answer.


How many ways 4 digits may be selected from Mathematics?

We have 11 digits. We have repeatition of A, T, M. Thus we have 8 digits. We have choices

like all different digits, or 2 common and 2 different digits or 2 pairs.

All different : 8c4 = 70 1 pair and 3 different digits: 3c1 *7c2 =63 2 pairs from 3 = 3c2 = 3 Total = 136


In how many ways can 9 students sit on a bench to be photographed, if 2 particular students want to sit at corner positions only?

Corner positions are occupied, so we have 7 positions left. We have 7!. The corner positions can be changed.

Thus answer is 7! * 2 = 10080 answer.


In how many ways can I make a necklace from 9 jewels that I have ?

Formulae = (n-1)! / 2 =8!/2 =20160 answer.


A boat’s crew consist of 8 men, 3 of whom can row only on one side and 2 only on the other. The number of ways in which the crew can be arranged is ?

We have to take equal number of persons on both the sides of the boat. Thus we have to take 4 persons on each side. We have 4 seats on both sides. Thus we have total 4! Choices on one side, thus total number of choices are 4!*4! (with 3 on one side and 2 on other). However, we have 3 persons who can sit on either side. So let us multiply 576 *3, we get 1728. answer.
