Question

A vendor purchase bananas at rupees 40 per dozen and sold them at 10 for rupees 36 find his gain or loss percent

Answer 1

Hey friend,

If my understanding is right according to your question, the merchant sold 10 bananas for rupees 36 and so there is 2 left out. With that in mind the calculations is proceeded.

Cost Price: 40/12 = 3.33 rupees/banana

Selling Price: 36/10 = 3.6 rupees/banana
Therefore it is 43.2 for 12 bananas

Profit= Selling Price- Cost Price
=43.2-40 = 3.2
Therefore 
Profit % = 3.2/40*100 
= 8% profit

Hope this helps..

Answer 2

Answer:

Step-by-step explanation:

Cost Price 1240​=3.33 rupees/banana

Selling Price 1036​=3.6 rupees/banana

Therefore,

It is 43.2 for 12 bananas

Profit=Selling Price−Cost Price

=43.2−40=3.2

Therefore,

Profit %=403.2​×100

=8% profit

Hence, this is the answer.
