Hamed is 7 years older than his brother Shaquib, who is twice as old as their younger sister Lopa. If Lopa is 15 years younger than Hamed. Then how old is Shaquib?

A 8 years

B 12 years

C 16 years

D 20 years

Solution

Correct Answer: Option C

Lopa = x

Shaquib = 2x

Hamed = 2x + 7

Now,

A/Q,

2x + 7 - x = 15

x + 7 = 15

x = 15 - 7

x = 8

2x = 2*8 = 16
