Explanation:

Let age of Aman’s father at time of marriage
= x years
So, age of Aman’s mother at time of marriage
= (x – 3) years
And, age of Aman’s father at time when he born
= (x + 3) years
Age of Aman’s mother at time when he born
= x years
Let, Age of Aman = y
Present age of Aman’s father = (x + 3 + y) years (given present Aman is 20 years younger than his mother)
So, present age of Aman’s father = (23 + y) years
And present age of Aman’s mother = (20 + y) years
ATQ –

253 + 11y = 260 + 10y
y = 7
So, Aman’s parents got married (7 + 3) = 10 years before
