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. 2000 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. 10000 for 4 months and received Rs. 2000 as profit.Solution
Ratio of profits received by A, B and C= (10000 times; 4):(12000 times; 4):(14000 times; 4) = 5:6:7 Therefore, total profit received = 2000 times; (5 + 6 + 7)/5 = Rs. 7200
