Question

the selling price of 11 articles is equal to the cost price of 13 articles. find the gain percent​

Answer 1

Answer:

Step-by-step explanation:let the CP of one article be x

so the cp of 13 articles will be 13x

and the cp of 11 articles will be 11x

we know that sp of 11 aticles is equal to the cp of 13 articles=13x

gain= 13x- 11x

gain= 2x

gain %= 2x/11x x 100

gain%= 200/11 %
