Question

A began business with Rs 45000 and B joined afterwards with Rs 30000. At the end of a year. the profit is divided in the ratio 2:1. When did H join?

• A. 3 months after
• B. 6 months after
• C. 8 months after
• D. 9 months after
• E. None of these

Answer 1

The correct option is D 9 months after

Suppose B joined after K months
$\therefore$ Profit is divided in the ratio of
$45000\times 12:30000\times K$
$\therefore \frac{45000\times 12}{3000\times K}=\frac{2}{1}\Rightarrow 60000K=540000$
$\therefore K=9$
