Answer 2

Answer:

% Profit of selling 40 eraser is 42.857

Step-by-step explanation:

Given:

Selling Price of 40 erasers = cost price + selling price of 12 eraser

As we know that,

(Selling Price = cost price + profit)

Let S.P of 1 eraser be Rs. 1

So, S.P of 40 eraser =Rs.40

S.P of 12 eraser= Rs.12

According to question,

Profit of selling 40 erasers = Rs.12

C.P of 40 eraser = Rs. 40 - Rs. 12      (C.P = S.P - profit)

                            = Rs. 28

% profit = (profit/C.P) × 100

             = (12/28) × 100

            = 42.857 %
