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 seven years from now?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 37 : 32.
Let, the ages of Gyanendra and Arbind be 6x and 5x, respectively
According to the question
⇒ 6x + 5x = 55
⇒ 11x = 55
⇒ x = 5
So, the present age of Gyanendra = 6x = 6 × 5 = 30
The present age of Arbind = 5x = 5 × 5 = 25
Hence, their age ratio after seven years = (30 + 7) : (25 + 7) = 37 : 32
