Correct answer: A
Let the father's present age be F. Then the mother's present age is F - 3.
Aman is 20 years younger than his mother, so Aman's present age is F - 23.
After 3 years, (F + 3) : (F - 3 + 3) = 11 : 10, so (F + 3) : F = 11 : 10.
10F + 30 = 11F, hence F = 30. Mother's age = 27 and Aman's age = 7.
Aman was born 3 years after the marriage, so the marriage happened 7 + 3 = 10 years ago.
