Answer 1

Answer:

CP of 25 dozen bananas=Rs.12per dozen

CP of 300 bananas=Rs.300

Profit on whole transaction=Rs.24

Therefore Total selling price=300+24=Rs.324

SP of 10 dozen bananas=Rs 15 per dozen.

SP of 120 bananas=Rs.180

SP of 12 dozen bananas=Rs.10 per dozen

SP of 144 bananas=Rs.120

Remaining bananas=300-(120+144)=36=3 dozen

The SP of these bananas must be Rs.324-(180+120)=Rs.24

Therefore SP of each dozen of remaining banana must beRs.
