Question

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

Answer 1

Answer: (A)

$32$ years, $23$ years

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 $y=23$.
