Text Solution

Verified by Experts

The correct Answer is:
D
Let present age of Rajendra = x years.
Then, present age of Rajendra.s brother
= (x + 6) years.
Present age of Rajendra.s father
`= [(x + 6) + 32]` years
`= (x + 38) ` years
And present age of Rajendra.s mother
`= [(x + 38) – 3]` years = `(x + 35) ` years
So, present age of Rajendra.s sister
`= [(x + 35)-25] `years = `(x + 10)` years
Therefore, required age of Rajendra.s sister when he was born `= {(x + 10) – x} = 10 `years.
