Question

harish purchase 50 dozen bananas for rupees 135 .five dozen bananas could not be sold, because they were rotten. at what price per dozen should harish sell the remaining bananas so that he could make a profit of 20%?​

Answer 1

Step-by-step explanation:

ANSWER

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

Bananas left after removing 5 dozen rotten bananas =45 dozens

Effective CP of one dozen bananas =Rs.135/45=Rs.3

Calculating the price at which Harish should sell each dozen bananas to make a profit of 20%(or1/5), we get

Profit%=Gain/CP=(SP−CP)/CP

51=3SP−3

SP=Rs.3.60

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