Question

Sachin is younger than Rahul by 7 years. If their ages are in the respective ratio of 7 : 9, how old is Sachin?

• A. 16 years
• B. 18 years
• C. 28 years
• D. 24.5 years
• E. None of these

Answer 1

The correct option is D 24.5 years

Let Rahul's age be x years.
Then, Sachin's age = (x - 7) years.
∴x−7x=79∴x−7x=79
Hence, Sachin's age = (x - 7) = 24.5 years
