My brother was 5 years old when my sister was born. My father was 31 years old when my brother was born while my mother was 29 years old when I was born. If my sister is 2 years elder to me, then what was the sum of ages of my father and mother when my sister was born? Correct Answer 63 years

Given:

My sister is 2 years elder to me and my brother was 5 years old when my sister was born.

Hence, eldest one is my brother then my sister who is 5 years younger to him and then I am the youngest one, 2 years younger to my sister.

As my father was 31 years old when my brother was born;

∴ Age of my father when my sister was born (born after 5 years when my brother was born) = 31 + 5 = 36 years

And

As my mother was 29 years old when I was born;

∴ Age of my mother when my sister was born (born before 2 years when I was born)

= 29 – 2 = 27 years

Hence,

Required sum = 36 + 27 = 63 years
