The respective ratio between the present age of Manikantan and Deepan is 2:D, Manikantan is 12 years.Younger than parthasarthy. Parthasarathy’s age after 12 years will be 48 years. The difference between deepan’s and Manikantan’s age is same as the present age of Parthsarahty. What will come in the place of D?
d)None of these.

Difference between Deepan and Manikantan is same as the age of Parthasarathy =36
Ratio of the age of Manikantan: Deepan=24:60=2:5
So D=5. Hence answer is d)None of these.
