Question

A man purchased 20 dozen mangoes for rs.1000 out of these 40 mangoes were rotten and could not be sold. At what rate per dozen should be sell the remaining mangoes to make a profit of 30%.

Answer 1

Answer:

78 per dozen

Step-by-step explanation:

1000 for 20 dozen

1 dozen = 1000/20 = 50

40 rotten mangoes = 3.3 dozen

remaining good mangoes = 16.66 dozen

cost of 16.6 dozen is 1000

profit of 30% = 1000 + 30/100 × 1000 = 1300

selling price is 1300 for 16.66 dozen

rate per dozen = 1300/16.66 = 78
