Question

A man bought bananas at the rate of 10 for ₹ 45 and sold at the rate of one dozen bananas for ₹51. Find his gain or loss per cent

Answer 1

THE SELLING PRICE OF 12 BANANA = 45
SP OF ONE BANANA=51/12
                                       =4.25
SP OF 10 BANANAS = 4.25*10=42.5
LOSS=CP-SP
LOSS=45-42.5
LOSS=2.5
LOSS%=LOSS/CP*100
LOSS%=2.5/45*100
LOSS%=250/45
LOSS%50/9
LOSS%=5.56%
