Question

all question s are solve not give answer directly

Answer 1

answer for ques. 9 is 102 since all the given numbers in the question are divisible by 3 and 102 is the only number in given options which is divisible by 3
answer for ques. 2 is sister in law (P and Q are brothers so their son will be cousins and one cousin's wife is another cousin's sister in law)

Let A's present age be x
B's present age be y
C's present age be z
9 years later,
9+y=x
9+y-x=0
y-x=-9
x-y=9 ......(1)

3 years later,
A's age = 3+x

4 years ago,
B's age = y-4

According to the question,
(x+3)+(y-4)=76
x+3+y-4=76
x+y-1=76
x+y=77 ......(2)

adding equation (1) and (2)
x + y = 77
x - y = 9
...................
2x = 86
x = 43

x - y = 9
43 - y = 9
-y= -34
y= 34

A.T.Q,
z = y/2
=34/2
= 17
after 10 years,
z= 17 + 10
= 27
so age of C after 10 years =z= 27 years (ANSWER)
