Question : 17 of 40

Marks: +1, -0

The ages of Surabhi and Neerja are in the ratio of 6 : 7 respectively. After 6 years the ratio of their ages will be 15 : 17. Find the age of Neerja.

Solution:

Let the present ages of Surabhi and Neerja are 6x and 7x years respectively; then,

{6x+6}/{7x+6}

{15}/{17}

⇒ 102x + 102 = 105x + 90
⇒ 3x = 12
∴ x = 4
Hence, present ages of Neerja = 7 × 4 = 28 years
