Jitin's age 3 years from now will be double the average of Jitin's current age and his age 8 years ago. What was Jitin's age 5 years ago?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 6 years.
Let Jitin's current age be x years
The average of Jitin's current age and his age 8 years ago = [x + (x - 8)]/2 = (2x - 8)/2 = (x - 4)
So, x + 3 = 2(x - 4)
⇒ x + 3 = 2x - 8
⇒ x = 11
⇒ x - 5 = 11 - 5 = 6
Therefore, Jitin's age 5 years ago was 6 years.
