Question

A grocor purchased five dozens of bananas for rupoos one fifty.Six of the bananas where ratten and had to be thrown away. He sold the remaining bananas at rupees fifty per dozen. What is the profit or loss​

Answer 1

Answer:

The cost price of 50 dozens bananas that Harish purchased, CP=Rs.135

Bananas left after removing 5 dozens of rotten bananas =45 dozens

Now, the effective CP of one dozen bananas =Rs.135/45=Rs.3

The price at which Harish should sell each dozen bananas to make a profit of 20%;

Profit%=Gain/CP=(SP−CP)/CP

10020=3SP−3

SP=Rs.3.60

Grocer should sell the bananas at Rs.3.60 a dozen in order to make a profit of 20%.
