P, Q, and R started a business with their investments in the ratio $3:5:1$ respectively. After 5 months, P invested the same amount as before, but Q withdrew $\tfrac{2}{5}$ of their investment. If the total profit at the end of one year is Rs. 3,450, find the profit earned by R.
- Rs.315
- Rs.420
- Rs.360
- Rs.540
Correct answer: Rs.360
Solution
In partnership problems, profit is divided in proportion to capital multiplied by time. After 5 months, P continues with the same investment, while Q's investment reduces to $\tfrac{3}{5}$ of the original; R remains unchanged throughout. Using the time-weighted investments, R's share comes out to Rs. 360.
