Question
The age of Kiran 4 years ago was 10% more than the present
age of Deepa. 4 years hence, the ratio of their ages will be 5:4. Find the difference between their present ages.Solution
Let the present age of Deepa be ‘x’ years
Therefore, present age of Kiran = (1 + 0.1)x + 4 = 1.1x + 4
According to the question,
(1.1x + 4 + 4) / (x + 4) = 5/4
Solving the equation, we get x = 20 years
Then, Kiran's age = 26 years
Required difference = 26 – 20 = 6 years
