Ratio between the present ages of Ram and Ramesh is 3 : 5
After 7 years the ratio of their ages will be 4 : 5.
Calculation:
Let the present age of Ram and Ramesh be 3x and 5x
According to the question,
\(\frac{3x +7}{5x + 7} = \frac{4}{5}\)
⇒ 15x + 35 = 20x + 28
⇒ 35 - 28 = 20x - 15x
⇒ 5x = 7
⇒ x = 7/5
So, the present age of Ramesh = 5 × 7/5
⇒ 7 years
∴The present age of Ramesh is 7 years.
