Three years ago, Rahul was three time as old as Sahil. 6 years from now, Rahul will be only twice as old as Sahil. What is present age of Rahul and Sahil ?
Answer & explanation
Correct answer: option 1
3 years ago ratio of age of Rahul and Sahil = 3 : 1
After 6 years from present = 2 : 1
ATQ,
⇒ \(\frac{3R + 9}{1R + 9}\) = \(\frac{2}{1}\)
⇒ 3R + 9 = 2R + 18
⇒ 1R = 9
⇒ 3 years ago age of Rahul = (3 × 9) = 27 and
age of Sahil = (1 × 9) = 9
Now,
Rahul's present age => 27 + 3 = 30 years
Sahil's present age => 27 + 3 = 12 years
