Answer 2

Let, the age of Vinu be 'x'.

Age of Manu = x + 10

After 5 years :

Age of Vinu = x + 5

Age of Manu = x + 10 + 5 = x + 15

According to the problem :

x + 15 = 2 ( x + 5 )

x + 15 = 2x + 10

2x - x = 15 - 10

x = 5.

Age of Vinu = x = 5 years

Age of Manu = x + 10 = 5 + 10 = 15 years.

Option - D is the answer.
