Rahim is now 14 years older than Karim. If in 10 years Rahim will be twice as old as Karim, how old will Rahim be in 5 years?

A 9

B 19

C 21

D 23

Correct Answer: Option D

Karim = K

Rahim = K + 14

Now,

2(k+10) = K + 14 + 10

or, 2K + 20 = K + 24

or, 2K - K = 24 - 20

or, K = 4

Thus, Rahim is right now = K + 14 = 4 + 14 = 18

After 5 years, Rahim will be = 18 + 5 = 23
