Answer 2

Answer:

8 Rupees /dozen

Step-by-step explanation:

According to the information provided in the question it is given as

Cost of banana =250

Gain =20% =

Selling price

$\frac{250\times 120}{100}\\SP= 300$

Number of banana which is at good condition=

$=(40\times 12 - 30)\\=450$

Now selling price of  450 bananas= 300

Selling price of 12 bananas =

$\frac{300}{450} \times 12\\= 8$

Hence the remaining banana should be sold at the rate of 8 rupees for gaining a profit of 20 %
