A B and C start a business and their investments are in the ratio 4 3 6 Both A and B starts the busi...........

Explanation:

After a year C gets salary = 500*6 = Rs 3,000 [Since C was for 6 months in the business with each month earning 500] So 10% of total profit after a year = 3,000
Total profit = Rs 30,000
A invested for 12 months, B for 12, and C for 6 months
Ratio of profit shares =
4*12 : 3*12 : 6*6 = 4 : 3 : 3
Profit left after deducting salary of C = 30,000 – 3,000 = 27,000
So share of A = [4/(4+3+3)] * 27,000 =10800
