The cost price of 400 lemons is equal to the selling price of 320 lemons. Then the profit percent is

To find the profit percentage, we need to calculate the profit first.

Given:
Cost price of 400 lemons = Selling price of 320 lemons

Let's assume the cost price of each lemon is x.

Cost price of 400 lemons = x * 400
Selling price of 320 lemons = x * 320

Since the cost price of 400 lemons is equal to the selling price of 320 lemons, we can equate the two:

x * 400 = x * 320

Now, let's solve this equation to find the value of x:

Dividing both sides by x:
400 = 320

This means the cost price of each lemon (x) is canceled out, and we are left with the equation 400 = 320, which is not possible.

Since we cannot determine the cost price and selling price, we cannot calculate the profit percentage.

cost per lemon = 1/400 = .0025

revenue per lemon = 1/320 = .003125
profit per lemon =
100(.003125-.0025)/.0025
=25%
