Correct Answer - Option 3 : 17 years
Vijay is 8 years younger than Amit.
Let the age of Amit be 'a' years.
So, age of Vijay = (a - 8) years
The sum of the current ages of Vijay and Amit is 42 years.
According to question:
a + a - 8 = 42
⇒ 2a = 42 + 8
⇒ 2a = 50
⇒ a = 50 ÷ 2
⇒ a = 25
The current age of Vijay = a - 8 = 25 - 8 = 17
Hence, ‘17 years’ is the correct answer.
