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.
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
