4th ques... It's ans is 18 2/11%

Answer 2

Answer:

$18\frac{2}{11}\%$

Step-by-step explanation:

Let the cost price and the selling price of each article are x and y respectively,

So, the selling price of 11 articles = 11y,

And, the cost price of 13 articles = 13x

According to the question,

11y = 13x

$\implies y = \frac{13}{11}x$

Hence, gain percentage = $\frac{y-x}{x}\times 100$

$=\frac{\frac{13}{11}x-x}{x}\times 100$

$=\frac{13x-11x}{11x}\times 100$

$=\frac{200}{11}$

$=18\frac{2}{11}\%$
