Q1: Ayush was born two years after his father's marriage. His mother is five years younger than his father but 20 years older than Ayush who is 10 years old. At what age did the father get married ?

ANS:A - 23 years

Explanation: Ayush's present age = 10 years. His mother's present age = (10 + 20) years = 30 years. Ayush's father's present age = (30 + 5) years = 35 years. Ayush's father's age at the time of Ayush's birth = (35 - 10) years = 25 years. Therefore Ayush's father's age at the time of marriage = (25 - 2) years = 23 years.
