Ravi’s age is $\frac{3}{5}$ of Shyam’s age. After x years the ratio of the ages of Ravi and Shyam becomes 5 : 7. If initially the sum of their ages is 32, then what is the value of x?
Answer & explanation
Correct answer: option 3
Ravi : Shyam
3 : 5
⇒ (3 + 5)units = 32
⇒ 8 units = 32
⇒ 1 unit = 4.
After x years,
Ravi : Shyam
5 : 7
⇒ (5 - 3)units = 2 units = 2 x 4 = 8.
Therefore, value of x is 8.
