Answer and Explanation.
1. F + C + T = 100-------------eq1
15F + C + 0.25T = 100-------------eq2
eq1=eq2 .solve to get F=3T/56 ;F=3,T=56,C=41
2. a) There is no need to consider their meeting pt at all.the train has been
running for 90miles/(60miles/hr)=1.5hrs.bird flies till train reaches destination
frm strting pt.so bird flies for1.5hrs at the vel given(90).so
dist=1.5*90=135miles
b) time of train=1hr.so dist of bird=60*1=60miles
3. (a) u don't need to sum it up.since it's a knock out only 1 person emerges
winner finally.so15+1=16is answer.becos after15 matches finally we shud've
15losers and 1winner.
(b) 49:its always one less than no of players as per the idea given above.so no
need to check okay cos its always true.ans is 49.
4. Let x= current age
4(x+4)+5(x+5)=10x ;so x=R 41 years
5. 37(x-y)=x^2-y^2. u no tht x^2-y^2=(x-y)(x+y).so (x-y) cancels on both
sides to give x+y=37.so sum of unequal halves=37 which is the req answer.
6. R ans:7 teams okay.for a match u need 2 teams.suppose there r totally 'n
'teams.
Now uve to choose 2 teams out of 'n' teams.so answer =no of such choices=no.
of possible combinations. So we've ans = nC2(ncombination2)=21;solve to get
n=7.
Sol: n(n-1)/2=21. so n=7.if u don't understand c the graph below
each team plays no. of matches=no of teams ahead of it. One bar '|' represents
one team.
| | | | | | | ------------7
6 5 4 3 2 1 0 -----------21
last team is written as 0 matches becos this team has already played with all
other teams-hence sum of matches =6+5+4+3+2+1=21 which is correct only if
no of teams =7
7. R 14
1. G+2=j-2
2. 2(G-2)=J+2.
solve these 2 to get
J=14
8. a). Sol:each mky takes 8 min to eat a banana
b).ans:8m=48 m=6
9. Use sets and venn diagram to solve such questions.a,b ,aub,anb etc.
12=tennis+leave
18=jog +leave
so jog-tennis=6
again jog+tennis=14.so solve and get jog=10,leave=8,tennis=4.so tot=22
10. Ans= 32*2 + 30*2=124
