The age of A is twice that of B. The Sum of their present ages is 60. What will be the sum of their ages 5 years hence?

Correct option is B

Let the age of B = x
Therefore, the age of A be 2x
As per question
x + 2x = 60
x = 20
Age of A = 40, B = 20
The sum of their ages 5 years hence = (40+5) + (20+5) = 70
