Question
P started a business with an investment of Rs.10000,
after 6 months Q joined him with Rs.12000 and after another 6 months R joined them with Rs.15000. If after end of two years profit share of Q is Rs.9000, then what is the total profit earned by them?Solution
Profit is shared based on investment × time. P: 10000 × 24 = 240000 Q: 12000 × 18 = 216000 R: 15000 × 12 = 180000 So profit ratio = 20:18:15 Total parts = 53 Q's 18 parts = Rs. 9000 → 1 part = Rs. 500 Total profit = 53 × 500 = Rs. 26,500
