Present ages of Sameer and Anand are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively. What is Anand's present age in years?

A 24

B 27

C 40

E None of these

ANS:A - 24

Let the present ages of Sameer and Anand be 5x years and 4x years respectively.

Then, 5x + 3 = 11
4x + 3 9
 9(5x + 3) = 11(4x + 3)  45x + 27 = 44x + 33  45x - 44x = 33 - 27  x = 6.  Anand's present age = 4x = 24 years.
