Question
A dishonest shopkeeper marks up the price of his produce by
40% on the cost price and sells it providing a discount of 25%. If he uses 800 gram as weight in place of 1 kg, what is his overall percentage profit?Solution
Let a customer believes to have bought 1 kg of produce. So, he pays for 1 kg but is actually provided with only 800 gm.
Let the C.P of the produce be Rs 1 per gm
M.P of the produce = Rs 1.4 per gm
S.P of the produce = 1.4*(75/100) = Rs 1.05 per gm
So, S.P of the produce sold to customer = 1.05*1000 = Rs 1050
C.P of produce sold to customer = 1*800 = Rs 800
Percentage profit = ((1050 - 800)/800)*100% = 31.25%
