1. The ages of Sonal and Manoj are in the ratio of 7:5. Ten years hence, the ratio of their ages will be 9:7. Find the present a

sesenic [268]

Answer:

Ratio of present ages of Sonal and Manoj = 7:5

Let us consider the ages of Sonal and Manoj to be 7x yrs. and 5x yrs. respectively.

After 10 years, ratio of their ages = 9:7

A/q, 7x+10/5x+10 = 9/7

or 9 (5x+10) = 7 (7x+10)

or 45x + 90 = 49x + 70

or 49x - 45x = 90 - 70

or 4x = 20

or x = 20/4 = 5 .

Therefore, present age of Sonal = 7x yrs. = 7 x 5 yrs. = 35 yrs.

present age of Manoj = 5x yrs. = 5 x 5 yrs. = 25 yrs.
