Answer 2

The profit percent is 42.857%

Step-by-step explanation:

Let the SP of 1 eraser be Re.1

So, SP of 40 erasers Rs.40

We are given that a trader sold 40 erasers and earned a profit equal to the selling price of 12 erasers

SP of 12 erasers = Rs.12

Profit of selling 40 erasers = Rs.12

CP = SP-Profit = 40-12 = Rs.28

Profit % = $\frac{Profit}{CP} \times 100 = \frac{12}{28} \times 100=42.857\%$

Hence The profit percent is 42.857%
