49. 

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 ?

[A]. 23 years
[B]. 25 years
[C]. 33 years
[D]. 35 years

Answer: Option A

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.

Take the age at which his father married x years.'
his mother=x-5(as mentioned)

Ayush was born 2 years after that so then
Father = x+2,
Mother = (x-5)+2 = x-3,
10 years after Ayush's birth.
Ayush = 10(as mentioned)
Father = x+10 and also 5 years older than mother,30+5=35
Mother = x-5+10 = x+5 and 20 years older than Ayush,10+20=30.

Now his father got married before(10+2)years.
so, his father got married when he was 35-(10+2)years.
Ans = 23.
