Friends…!
Let A’s present age be x.
Thus A’s mother's age 10 years ago was 4 (x - 10)
A’s mother's age after 10 years will be 2 (x + 10)
As per statement, A's mother was 4 times as old as A ten years ago. After ten years, she will be twice as old as A. Accordingly
2 (x + 10) - 4 (x - 10) = 20
2x + 20 - 4x + 40 = 20
2x - 4x + 60 = 20
—2x = 20 — 60
—2x = —40
x = 40/2
x = 20
Thus A’s present age is 20 years.
