A invests Rs. 40,000 for 12 months and B invests Rs. 60,000 for 8 months in a business. Out of a total profit of Rs. 18,000, what is A's share?
सही उत्तर: ख) Rs. 9,000
Profit is shared in the ratio of capital × time: 40,000 × 12 : 60,000 × 8 = 4,80,000 : 4,80,000 = 1 : 1. So A gets Rs. 9,000. Rs. 7,200 comes from using capital alone (2 : 3).
