Answer 1

Answer:

Step-by-step explanation:

Cost price of bananas = 24;

In order to gain 20%;

the selling price = (100+Gain%)/100 x cost price;

Selling price = (100+20)/100 x 24;

= 120/100 x 24 = 28.8

In order to gain 20 % the Selling price of bananas is Rupees 28.8

Answer 2

Answer:

20

Step-by-step explanation:

Given If bananas are bought at the rate of 24 for a rupee, how many must be sold for a rupee in order to gain 20%?

Selling price of 24 bananas will be (100 + 20)% of Re 1

                                    = 120 / 100 = 6/5 Re

Now number of bananas sold for Rs 6/5 is 24

Therefore for 1 Re will be 24 / 6/ 5 = 24 x 5/6 = 20

hence number of bananas to be sold for Re 1 will be 20
