Answer:
The present age of Ramesh is 20 years
The present age of Mahesh is 28 years
Explanation:
Let, The present age of Ramesh = 5x, and
The present age of Mahesh = 7x
After four years,
The age of Ramesh = 5x + 4
The age of Mahesh = 7x + 4
And
The ratio of thier age will be 3 : 4
So,
⇒ 4 (5x +4) = 3 (7x + 4)
⇒ 20x + 16 = 21x + 12
⇒ 20x - 21x = 12 - 16
⇒ -1x = - 4
⇒ 1x = 4
⇒ x = 4
★ Value of 5x :
⇒ 5 (4) ⇒ 5 × 4 ⇒ 20
★ Value of 7x:
⇒ 7 (4) ⇒ 7 × 4 ⇒ 28
Therefore,
The present age of Ramesh is 20 years
The present age of Mahesh is 28 years
