The ages of Krish and Vaibhav are in the proportion of 3 : 5. After 9 years, the proportion of their ages will be 3 : 4. Then the current age of Vaibhav is:
Answer: C
Let Krish's age be \(3A\) and Vaibhav's age be \(5A\)
\(\therefore(3A+9)/(5A+9) = 3/4\)
\(\Rightarrow 4 (3A + 9) = 3 (5A + 9) \)
\(\Rightarrow A=3\)
Therefore, Vaibhav’s age = 15 years.
