Question

• A. 5 ∶ 6
• B. 37 ∶ 32
• C. 32 ∶ 37
• D. 6 ∶ 5

Answer 1

Answer:

B. 37 ∶ 32

Solution: Given: Age of Gyanendra : age of Arbind = 6 : 5 Gyanendra + Arbind = 55 years Calculation: According to the question: ⇒ (6 + 5) = 11 units = 55 years ⇒ 1 unit = 5 years Age of Gyanendra = 6 units = 5 × 6 = 30 years Age of Arbind = 5 units = 5 × 5 = 25 years Gyanendra age after 7 years : Arbind age after 7 years = (30 + 7) : (25 + 7) ⇒ 37 : 32 ∴ The correct option is 2.
