Question

If the ratio cost price and selling price is 5:7 then the profit and gain is %

Answer 1

Step-by-step explanation:

Let the common multiplier of the given ratios be x.

Therefore,

Cost Price (CP) = 5x

Selling Price (SP) = 7x

Because, SP > CP

So, Profit = 7x - 5x = 2x

$Profit \: percent = \frac{Profit}{cp} \times 100 \\ = \frac{2x}{5x} \times 100 \\ = \frac{2}{5} \times 100 \\ = 2 \times 20 \\ = 40 \%$
