After 5 years the ratio of the ages of Akbar and Sameer will be 5:6. If the present age of Sameer is 25 years, then find after how much time the age of Akbar will be 40 years.

Explanation

Let the ages of Akbar and Sameer after 5 year be 5x and 6x respectively. Then, the present age of Akbar = (5x – 5) years Present age of Sameer = (6x – 5) years Now, 5x – 5 = 25 ⇒ x = 6 Present age of Akbar = 5 × 5 – 5 = 20 years So, Akbar will become 40 years old after 20 years.
