Question

A shop keeper bought 50 dozen bananas for ₹50 per dozen. If 22 bananas were found rotten and had to be thrown away, find the rate per dozen he should sell the bananas so as to gain 10% in whole transaction?​

Answer 1

Total price at which he purchased 50 dozen banana = 50*50=2500
72 banana are rotten ==> 6 dozens are rotten
now he is left with 44 dozens to be sold
Now 2500/100*110=2750 To earn 10 % profit he will have to sell 44 dozen at 2750
Therefore 2750/44= 62.5
Rs 62.5--> at which he will sell banana per dozen to earn 10 % profit.
