The ratio between the present ages of Ram, Rohan and Raj is 3 : 4 : 5. If the average of their present ages is 28 years then what would be the sum of the ages of Ram and Rohan together after 5 years ?
A). 56 years
B). 57 years
C). 58 years
D). 59 years
59 years
Let the present ages of Ram,Rohan and Raj be 3x, 4x and 5x years respectively.
∴ 3x + 4x + 5x = 3 x 28
= 12x = 84 = x = 84/12 = 7
Sum of the ages of Ram and Rohan after 5 years
