Arvind is now 40 years old and Asha is 25 years old. How many years ago from now was Arvind four times as old as Asha?
Given:
Arvind’s current age = 40 years
Asha’s current age = 25 years
Find (x): years ago when Arvind was four times Asha’s age
Solution:
If x years ago, then
Arvind’s age = 40 - x
Asha’s age = 25 - x
Condition: 40 - x = 4(25 - x)
40 - x = 100 - 4x
3x = 60
x = 20.
