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 ?
Answer: Option
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.

@All.
Here is the answer.
Ayush's mother is 20 years older than him.
The difference will be the same only when he was born.
So when he was born his mother was of 20 years. And their marriage happened before 2 years. So, she will be 18 at that time and his father was 5 years older so 23 years.

Ayush born only after 2 years of marriage.
So his mother is 5 years younger than his father.
M= F-5 before Ayush born;
And when Ayush was 10 years old her mother is 20 years older than him.
So,
M = 20+10.
= 30.
We HAVE
M=F-5,
30=F-5.
F=35.
Now when the father-mother marry means Ayush was not born;
So subtract 10years from Father's age =25.
And we know Ayush was born only after 2 years of their father's marriage,
So subtract 2 from 25.
Here we get 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.
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.
