The ratio between the ages of Ram and Mohan is 4 : 5 and that between Mohan and Anil is 5 : 6. If sum of the ages of three be 90 years, what is the age of Mohan ?
-
- 20 years
- 24 years
- 25 years
- 30 years
Correct Option: D
Here, ratio of ages of Ram, Mohan and Anil = 4 : 5: 6
Let their present ages be 4x, 5x and 6x years respectively.
then 4x + 5x + 6x = 90
⇒ 15x = 90
∴ x = 6
Hence, age of Mohan = 5 x 6 = 30 years
