COMPLETE QUESTION
My brother is 3 years elder to me. My father was 28 years of age when my sister was born while my mother was 26 years of age when I was born. If my sister was 4 years of age when my brother was born, then what was the age of my father and mother when my brother was born
EVALUATION
Let I am x years old
∴ My age = x years
My brother is 3 years elder to me
∴ Age of my brother
= ( x + 3 ) years
Again my mother was 26 years of age when I was born
∴ Age of my mother
= ( x + 26 ) years
Now my sister was 4 years of age when my brother was born
∴ Age of my sister
= ( x + 3 + 4 ) years
= ( x + 7 ) years
Again My father was 28 years of age when my sister was born
∴ Age of my father
= ( x + 7 + 28 ) years
= ( x + 35 ) years
∴ The age of my father when my brother was born
= ( x + 35 ) - ( x + 3) years
= 32 years
∴ The age of my mother when my brother was born
= ( x + 26 ) - ( x + 3) years
= 23 years
