Question 63

An article is sold at $$14\frac{2}{7}\%$$ profit. What is the ratio of the selling price to the cost price?

Solution

Let assume cost price = 100

profit %=$$14\frac{2}{7}\%$$

profit = $$14\frac{2}{7}$$ = $$\frac{100}{7}$$

Selling price = profit+ cost price

                        = $$\frac{100}{7}+100$$

                          = $$\frac{800}{7}$$

the ratio of the selling price to the cost price

=  $$\frac{\frac{800}{7}}{100}$$

 = $$8:7$$
