The ratio of present ages (in years) of a father and son is 15 : 8. Six years ago, the ratio of their ages was 13 : 6. What is the father's present age ?
Answer & explanation
Correct answer: option 3
ATQ ,
\(\frac{13x + 6 }{6x + 6 }\) = \(\frac{15}{8}\)
104x + 48 = 90x + 90
14x = 42
x = \(\frac{42}{14}\) = 3
Present age of Father = 13 × 3 + 6 = 39 + 6
= 45 years
