A man divided his share between his sons A and B in such a way that the interest received by A at 15\% p.a. for 3 years is double the interest received by B at 12\% p.a. for 5 years. In what ratio was his share divided?

(a)$\frac{2}{3}$

(b)$\frac{3}{2}$

(c)$\frac{3}{8}$

(d)$\frac{8}{3}$

Answer

Answer (as printed): D

Explanation

Let A's share $=₹ x$ and B's share $=₹ y$. Then, $\frac{x \times 15 \times 3}{100}=2 \times \frac{y \times 12 \times 5}{100} \Rightarrow 45 x=120 y$ $$\Rightarrow \quad \frac{x}{y}=\frac{120}{45}=\frac{8}{3} .$$
