A fruit seller purchased 3 dozen bananas at Rs.4 per banana. He sold all the bananas for Rs.180. He gains 25% in the entire transaction
Total number of bananas in 3 dozen = 12 × 3 = 36
Cost for one banana = Rs 4
Cost Price (CP) for 3 dozen bananas = Rs 4 × 36 = Rs 144
Selling Price (SP) = Rs 180
As SP > CP, he made a profit = Rs 180 - Rs 144 = Rs 36.
Profit% = 36144×100% = 25%
