The age of Rohit is 25% more than the age of Sachin. If the sum of their ages is 45 years, what is the difference between their ages?

Detailed Solution for Test: Problems on Ages - 2 - Question 2

To find the difference between Rohit and Sachin's ages:

- Let's say Sachin's age is x years.
- Rohit's age is 25% more, which is 1.25x.
- Given, their total age is 45 years: x + 1.25x = 45.
