The ratio of the age of Ram and Mukesh 10 years ago was 1 : 3. The ratio of their age five years hence will be 2 : 3, then the ratio of the their present age is?
Answer & explanation
Correct answer: option 2
Ram : Mukesh
1 : 3 → 10 years ago
2 : 3 → 5 years hence
ATQ,
\(\frac{x + 15}{3x + 15}\) = \(\frac{2}{3}\)
3x + 45 = 6x + 30
15 = 3x
x = 5
Therefore,
⇒ 10 years ago Ram's age = 5 yrs
⇒ 10 years ago Mukesh's age = 15 yrs
⇒ Present age of Ram = 5 + 10 = 15 yrs
⇒ Present age of Mukesh = 15 + 10 = 25 yrs
Ratio of present age = 15 : 25 = 3 : 5
