When a producer allows 36% commission on the retail price of his product, he earns a profit of 8.8%. What would be his profit if the commission is reduced by 24%?

The new profit is 49.6%.

Take retail price = 100; commission 36 leaves the producer 64.

64 = CP x 1.088 gives CP = 58.82.

New commission 12 leaves 88 for the producer.

Profit = (88 - 58.82)/58.82 x 100 = 49.6%.
