Question
Three persons A, B and C invested different amounts in a
business, which are in A.P. The amount invested by B is Rs. 1500 more than that of A. C invested the highest amount. Find the total profit received if all of them invested their sum for equal duration and A invested Rs. 9000 for 4 months and received Rs. 1000 as profit.Solution
Ratio of profits received by A, B and C= (9000 times; 4):(10500 times; 4):(12000 times; 4) = 6:7:8 Therefore, total profit received = 1000 times; (6 + 7 + 8)/6 = Rs. 3500
