The ratio of their present ages is 3:4
According to the question we are given,
The present age of Rohan and Sohan = 3 ∶ 4
5 years ago the ratio of their age = 2 ∶ 3
Calculation:
Let the age of Rohan and Sohan be 3x and 4x respectively.
5 years back their ages will be (3x – 5) and (4x – 5) respectively.
According to the question, ⇒ (3x – 5) ∶ (4x – 5) = 2 ∶ 3
⇒ (3x – 5)/(4x – 5) = 2/3
⇒ 9x – 15 = 8x – 10 ⇒ x = 15 – 10
⇒ x = 5
Hence as x = 5 we get,
Present age of Rohan = 3 × 5 = 15
Present age of Sohan = 4 × 5 = 20
Therefore the ratio of their present ages is 3:4
