Changaz invests Rs.6000 for an entire year in a business partnership, while Nasir contributes Rs.3000 for 6 months. If the total profit is Rs.240, what portion of the profit does Nasir receive?

Explanation

The profit share is based on the product of investment and time. Changaz's investment duration is 12 months, and Nasir's is 6 months. The ratio of their investments multiplied by time is (6000 × 12) : (3000 × 6) = 72000 : 18000 = 4 : 1. Therefore, Nasir's share is 1/5 of the total profit, which is (1/5) × 240 = Rs.48.
