Question

if rekha sells 16 articles for the same money as she pays for 20,her gain in percentage is

Answer 1

Answer: 25 %

Step-by-step explanation:

According to the question,

Selling price of 16 article= Cost price of 20 article

⇒$\frac{\text{Selling price}}{\text{Cost price}}=\frac{20}{16}=\frac{5}{4}$

Thus, the ratio between the selling price and cost price of the article = 5 : 4

Let the selling price = 5x

And, the cost price = 4x

Where x is any number,

Thus, the total profit percent

$=\frac{\text{selling price - cost price}}{\text{cost price}} \times 100$

$=\frac{5x-4x}{4x}\times 100$

$=\frac{x}{4x}\times 100$

$=\frac{100}{4}$

$=25\%$
