P owns 2/3 shares of a company and the rest of the shares is equally divided among Q and R. If the profit on each share increases from 5% to 7%, P earns an extra 800 rupees. The investment of R on the shares is

Solution

Let total shares of the company be $$6x$$

=> P = $$\frac{2}{3} * 6x$$ = Rs. $$4x$$

=> Q = Rs. $$x$$ and R = Rs. $$x$$

$$\therefore$$ $$4x \times 2\% = 800$$

=> $$4x \times \frac{2}{100} = 800$$

=> $$x = 10,000$$

$$\therefore$$ R's investment = $$x$$ = Rs. 10,000
