Question

If the cost price of 30 articles is equal to the selling price of 36 articles, what is the % profit or loss made by the merchant?​

Answer 1

Explanation:

Let the cost price of 30 articles be x.

The selling price of 36 articles will also be x.

Cost price of one article $= \frac{x}{30}$

Selling price of one article $= \frac{x}{36}$

There is obviously a loss.

$Loss=CP-SP=\frac{a}{30}-\frac{a}{36}=\frac{6a-5a}{180}=\frac{a}{180}$

$Loss Percent=(\frac{loss}{CP})(100) =[ (\frac{a}{180})(\frac{30}{a})](100)=(\frac{1}{6})(100)$

Loss % = 16.66%

Answer: 16.66% Loss

I hope this helps. :D

Answer 2

Answer:

% of loss 50/3%

Step-by-step explanation:

x/30--x/36=x/180 so % of loss = (3000x ÷180x)=50/3%
