Question

the cost price of 432 bananas is equal to the selling price of 360 banana then what is the gain percent

Answer 1

Given the Cost Price of 432 bananas = Selling Price of 360 Bananas

It is clearly observed that I bought 432 banans for X rupees and I sold 360 bananas with the same X rupees. The remaining bananas which was sell by me is a profit.

Let us consider 1 banana = Rs. 1

Cost Price (CP) = Rs. 432   ║ Selling Price (SP) = Rs. 360  ⇒ Profit = CP - SP = Rs. 72

Profit or gain percentage = ($\frac{72}{360} *100$) = 20%
