The present age of Rahim is five times the present age of his daughter, Savita. Seven years from now, Rahim will be three times as old as Savita. What is the present age (in years) of Rahim?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 35.
Let, the present age of Rahim be R and the present age of his daughter be S
According to the question,
⇒ R = 5 × S.. (1)
After seven years
⇒ R + 7 = 3(S + 7)
Put the value of R from equation (1)
⇒ 5S + 7 = 3S + 21
⇒ 2S = 14
⇒ S = 7
Hence, the present age of Rahim is R = 5S = 5 × 7 = 35 years
