Question

1. Find the profit or loss per cent in the following cases.

(I) Selling price = 1600 and cost price = 1800.​

Answer 1

Here we are given the selling price and cost price

Selling price (SP) = 1600

Cost price ( CP) = 1800

We have to find out the profit or loss percent

Now, as the SP is less than the CP, there is a loss

Loss = CP - SP

        = 1800 - 1600

        = 200

Loss % = $\frac{loss}{CP} \times 100$

Putting the values in the formula

Loss % = $\frac{200}{1800} \times 100$

            = 11.11

Therefore, the loss percent will be 11.11 %
