Rahim is now 10 years youngere than karim. If in 5 years karim becomes twice as old as rahim, how old will rahim be in 3 years ?

A 8

B 6

C 14

D 18

Correct Answer: Option A

Let, Karim is x years old

So, Rahim = (x-10) years old

According to question,

(x+5) = 2(x-10+5)

=> x+5 = 2x-10

=> x=15

So, After 3 years Rahim will be = x-10+3 = 8 years (Ans.)
