Ages 37Q

37.	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: Option D

Explanation:

Let Rahul's age be x years.

Then, Sachin's age = (x - 7) years.

	x - 7	=	7
	x		9

 9x - 63 = 7x

2x = 63

 x = 31.5

Hence, Sachin's age =(x - 7) = 24.5 years.
