Answer 2

Susant will be 22 years old.

Given : Prasant is 5 year old and Susant's age is thrice that of prasant.

To find : Age of Susant when Prasant is 12 years old.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the age of Susant)

Prasant's present age = 5 years

According to the data mentioned in the question,

Susant's present age = 3 × Prasant's age = 3 × 5 = 15 years

Number of years after which Prasant will become 12 years old :

= 12 - Prasant's present age

= 12 - 5

= 7 years

So, after 7 years the age of Susant will be :

= Susant's present age + 7

= 15+7

= 22 years

(This will be considered as the final result.)

Hence, Susant will be 22 years old.
