Download Solution PDFGiven:
Four years ago age ratio of Ram and Rahul = 3 : 4
Present age ratio of Ram and Rahul = 17 : 22
Calculation:
Four years ago age ratio of Ram and Rahul = 3x : 4x
According to the question
(3x + 4)/(4x + 4) = 17/22
⇒ 22 × (3x + 4) = 17 × (4x + 4)
⇒ 66x + 88 = 68x + 68
⇒ 68x – 66x = 88 – 68
⇒ 2x = 20
⇒ x = 10
Present age of Ram = 3 × 10 = 30 + 4 = 34
Present age of Sunil = 34 – 5 = 29 years
∴ the correct answer is 29 years.
