Question

A shopkeeper buys an article for Rs400 and marks it for sale ata a price that may give him 80% of profit on his coat. He, however gives 15% discount on the marked price to his customer. Calculate (i) the marked price of the article, (ii) the discount in rupees given to the customer, (iii) the actual percentage profit made by the shopkeeper

Answer 1

CP=₹400
P=80%
SP=CP×((100+P)÷100)
=400×((100+80)÷100)
=400×(180÷100)
=400×180÷100
=4×180
=₹720
D=15%
MP=(SP×100)÷100-D
=72000÷85
=₹847.05
D=D%×MP
=15÷100×847.05
=₹127.05
