A fruit seller purchased 3 dozen bananas at ₹ 4 per banana. He sold all the bananas for ₹ 180. Find the profit/loss percent for the deal.
25% profit
CP of one banana = ₹ 4
CP of 3 dozen (=36) bananas
= 36 x ₹ 4
= ₹ 144
SP of the bananas = ₹ 180
Since SP > CP, we have a profit.
Profit = SP - CP = ₹ 180 - ₹ 144 = ₹ 36
Profit % =ProfitCP×100
=₹ 36₹ 144×100 =14×100
=25%
