SSC CHSL Model Paper 3

Question : 36 of 100

Marks: +1, -0

Rahim and his uncle differ in their ages by 30 years. After 7 years, if the sum of their ages is 66, what will be the age of the uncle ?

Solution:

Let uncle’s present age = x
Rahim's present age = y

y - x = 30

....(i)
After 7 year

(x + 7) + (y + 7 ) = 66

x + y + 14 = 66

x + y= 52

....(ii)
combining (i) and (ii) we get

(x + y= 5 2) + (x -y = 3 0 )

2x=82

x=41

Uncle's age is 41
