Q.

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
Explaination:

 


Let Rahul's age be x years.


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

(x-7/x)=7/9

9x - 63 = 7x

2x = 63

x = 31.5

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