Answer 2

Given:

We have selling price of pen=72, loss%=40

To Find:

Cost price of pen?

Step-by-step explanation:

• Let the cost price be x

        Then loss will be = C.P-S.P=x-72

• Since, we have selling price=Rs. 72

• Loss% is given by the formula

             [tex]loss\%=\frac{Loss}{CP} \times100\\ 40=\frac{(x-72)}{x} \times100\\ x=\frac{100}{40} (x-72)\\ 2x=5x-150\\ -3x=150\\ x=50[/tex]

Thus,cost price will be Rs. 50
