Question

the cost price of 15 articles is equal to selling price of 12 similar articles. Find the gain or loss percent.​

Answer 1

Answer:

20%

Step-by-step explanation:

Suppose the cost of one article =x

Cost of 15 articles =15x

Selling price of 15 articles =12x

Loss=15x-12x=3x

Loss

$loss\% = \frac{loss}{cost \: price} \times 100$

$loss\% = \frac{3x}{15x} \times 100 = 20\%$
