Answer» Correct Answer - Option 3 : 45 Given: 5 years ago, the ratio of the ages of Kaif and Raj was 8: 5. 3 years hence, the ratio of their ages will be 15: 10 Calculation Let the ages of Kaif and Raj 5 years ago be 8x and 5x years Present age of Kaif = 8x + 5 Present age of Raj = 5x + 5 According to the question, ⇒ ((8x + 5) + 3)/((5x + 5) + 3) = 15/10 ⇒ 80x + 50 + 30 = 75x + 75 + 45 ⇒ 5x = 120 – 80 ⇒ x = 8. Raj's present age = (5x + 5) = 45 years ∴ Raj’s present age is 45 years |
