Answer:

Concept: This question is from Ratio & Proportion chapter. Ratio means one given value is how much varies with another value.

Given: The ages of Sonu and Monu in the ratio of 3:5 and Sonu's age of 15 years

To Find: Age of Monu

Solution: let the age of Sonu and Monu are 3x and 5x.

Sonu's age 3x=15

x=5,    now put the value of x in Monu's age

5×5=25
