The ages of Gyanendra and Arbind are in the ratio 6 ∶ 5. If the sum of their ages is 55 years, then what will be the ratio of their ages after seven years from now?
A5 ∶ 6
B37 ∶ 32
C32 ∶ 37
D6 ∶ 5
Answer:
B. 37 ∶ 32
Read Explanation:
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.
