Question : 20 of 40

Marks: +1, -0

The difference between the ages of a boss and his subordinate is 16 years. Four years ago, the respective ratio of the ages of the boss and subordinate was 11 : 7. The present age of the subordinate is:

28 years
32 years
36 years
40 years

Validate

Solution:

Let the present age of the boss and his subordinate be (x + 16) and x years respectively; then

{x+16-4}/{x-4}

{11}/7

⇒ 7x + 84 = 11x – 44
⇒ 4x = 128
∴ x = 32 years
