40.

Ravi's brother is 3 years senior 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, what were the ages of Ravi's father and mother respectively when his brother was born ?

 [A]. 32 years, 23 years [B]. 32 years, 29 years [C]. 35 years, 29 years [D]. 35 years, 33 years

Explanation:

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. So, x - 28 = 4 or x = 32.

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 i.e. y - 23 = 0 or y = 23.

Ravi's mother 26 year old while Ravi born ...............(3). Ravi's sister 4 year old while Ravi's brother born .......(4). There for Ravi's father edge while Ravi's brother born was, 28+4=32 {From equation (2) & (4)}. There for Ravi's mother edge while Ravi's brother born was, 26-3=23 { From equation (1) & (3)}.
