🤔 Let’s solve the problem step by step!

Let Sachin’s age be 7x and Rahul’s age be 9x, since their ages are in the ratio of 7:9.

We know that Sachin is younger than Rahul by 7 years, so we can set up the equation:

9x – 7x = 7

Simplifying the equation, we get:

2x = 7

x = 7/2

x = 3.5

Now, we can find Sachin’s age by substituting x into his age equation:

Sachin’s age = 7x

= 7(3.5)

= 24.5

Since age cannot be in fractions, we can assume that the ages are in years and months. However, for simplicity, we can round down to the nearest whole number.

The final answer is: 24
