Answer 2

Answer:

On finding sp when cp and profit or loss percent are given

In this method you can use proportion or formula.

If Profit % is given then selling price will be

       CP (100 + P%)

SP = ------------------

          100

To find SP when loss % and CP are given

        CP (100 - L%)

SP = ------------------

          100

Illustration 1 : Cost price = $450, Profit % = 5% find SP.

Step-by-step explanation:

Solution :

As profit percent is given, we use the following formula.

       CP (100 + P%)

SP = ------------------

          100

       450 (100 + 5)

SP = ------------------

          100

       450 x 105

SP = -------------

          100

       47250

SP = -----------

          100

∴ Selling price = $472.50
