Question

The ratio of the present ages of Geeta and her mother is 1: 5. After 7 years the ratio will be 3: 8. What is the present age of Geeta?
1. 7 years
2. 6 years
3. 5 years
4. 8 years

Answer 1

Correct Answer - Option 3 : 5 years

Given:

The ratio of the present ages of Geeta and her mother is 1: 5

After 7 years the ratio will be 3: 8

Calculation:

Let the present age of Geeta and her mother be x and 5x.

After 7 years, their ages = (x + 7) and (5x + 7) rspectively

New ratio = (x + 7)/(5x + 7) = 3/8

Or, x = 5 years

∴ Present age of Geeta is 5 years.
