business, which are in A.P. The amount invested by B is Rs. 1000 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. 18000 for 4 months and received Rs. 1800 as profit.Solution
Ratio of profits received by A, B and C= (18000 times; 4):(19000 times; 4):(20000 times; 4) = 18:19:20 Therefore, total profit received = 1800 times; (18 + 19 + 20)/18 = Rs. 5700
