Shobo’s mo

Let Shobo’s present age is x years.

Thus, his mother’s present age will be 6x years.

After 5 Years:
Shobo's Age = x + 5 years

Given, 
Shobo’s age five years from now will be one third of his mother’s present age

⇒ 3(x + 5) = 6x

⇒ 3x  + 15 = 6x

⇒ 15 = 6x – 3x

⇒ 3x = 15

⇒ x = 5

Hence, Age of Shobo = x= 5 years

Age of his mother = 6x = 6(5) = 30 years
