Correct Answer: 35 years
Solution : Let the present ages of A and B be 3$x$ and 5$x$ respectively. According to the question, $\frac{(3\text{x} + 5)}{(5\text{x} + 5)} = \frac{13}{20}$ ⇒ 60$x$ + 100 = 65$x$ + 65 ⇒ 5$x$ = 35 ⇒ $x$ = 7 The present age of B = 5$x$ = 5 × 7 = 35 $\therefore$ The present age of B is 35 years. Hence, the correct answer is 35 years.
