Question

when the price of pressure cooker was increased by 15%, the number of pressure cooker sold decrease by 15% what is the net effect on the sale

Answer 1

Let the original cost of each cooker be Re. 1 and let the number sold originally be 100. 
Total sale proceeds = Rs. (100 x 1) = Rs. 100

New rate = (115% of Re. 1 ) = Rs . 1.15
Number sold now = 85
∴ Sale proceed now = Rs. (1.15 x 85) = Rs. 97.75

So, there is a decrease of 2.25% in the money receipt.
