Question 15

The respective ratio between the present age of Manisha and Deepali is 5 : X. Manisha is 9 years younger than Parineeta. Parineeta's age after 9 years will be 33 years. The difference between Deepali's and Manisha's age is same as the present age of Parineeta. What will come in place of X?

Solution

Let the present age of Manisha be 5a

The present age of Deepali = Xa

The present age of Praneeta = 5a+9

Praneeta's age after 9 years = 5a+18=33

5a=15

a=3

The difference between Deepali's and Manisha's age is the same as the present age of Parineeta

Xa-5a=5a+9

3X-15=15+9

3X=39 ==> X=13

D is the correct answer.
