Formula given at last was wrong. Even though it gave right result. Consider this 2 chair sold at 500 each. One at 20% profit and another at 12% loss. Result would be 20/13 % overall profit. But by this formula 8 - 2.4 = 5.6% therefore this is wrong formula. Please clarify.

The answer which you have taken out is when both the profit and loss % is same that strategy you have used.... Please use the method a+b+a*b/100 taking a or b as profit or loss put plus sign for profit nd minus for loss you will get the answer as 52.5 % profit
