An article is sold at $$14\frac{2}{7}\%$$ profit. What is the ratio of the selling price to the cost price?
Let assume cost price = 100
profit %=$$14\frac{2}{7}\%$$
profit = $$14\frac{2}{7}$$ =Â $$\frac{100}{7}$$
Selling price = profit+ cost price
            = $$\frac{100}{7}+100$$
             = $$\frac{800}{7}$$
the ratio of the selling price to the cost price
=Â Â $$\frac{\frac{800}{7}}{100}$$
 = $$8:7$$
