Question

A man bought 10 bananas for Rs15 and sold a dozen of banana for Rs 15 .Find his gain or loss percent .

Answer 1

CP of 10 bananas = Rs 15
CP of 1. banana. = Rs 15/10 = Rs 1.50

SP of 12 bananas = Rs 15
SP of 1 banana. = Rs 15/12 = Rs 1.25

Loss = CP - SP
= 1.50 - 1.25
= 0.25

Loss percent = Loss/CP × 100
= 0.25/1.50×100
= 50/3 %
