One year ago, the ratio between Sumith’s and Akhil’s age was 4 : 3. One year hence, the ratio of their ages will be 5 : 4. What is the sum of their present ages?

12 years
15 years
16 years
24 years
Explanation:

Let Sumith’s age one year ago be 4x years and Akhil’s age be 3x years.
The present age of Sumith = (4x + 1) years
The present age of Akhil = (3x + 1) years
One year hence, Sumith’s age = (4x + 2) years and Akhil’s age = (3x + 2) years.
According to the question,
(4x + 2)/(3x + 2) = 5/4 => 16x + 8 = 15x +10
or x = 2
Therefore, the sum of their present ages = 4x + 1 + 3x + 1 = 7x + 2
= 7 x 2 + 2 = 16 years.
