Ravi's brother is 3 years elder to him. His father was 28 years of age when his sister was born while his mother was 26 years of age when he was born. If his sister was 4 years of age when his brother was born, the ages of Ravi's father and mother respectively when his brother was born were

A) 32 years and 23 years
B) 32 years and 29 years
C) 35 years and 29 years
D) 35 years and 33 years

Correct Answer:

A) 32 years and 23 years

Description for Correct answer:
When Ravi's brother was born, let Ravi's father's age = x years and mother's age = y years

Then sister's age = (x - 28) years

x - 28 = 4

x = 32

Hence when Ravi's brother was born his father was 32 years of age

Now, Ravi's age = (y - 26) years

Age of Ravi's brother = (y - 26 + 3) years

= (y - 23) years

Now, when Ravi's brother was born his age = 0 years

y - 23 = 0

y = 23

Hence when Ravi's brother was born his mother age was 23 years

Hence option (a)is correct
