The total cost price of 63 identical articles is equal to the total selling price of 54 of those articles. What is the gain or loss percentage?

Correct option is C

Given:

Cost Price of 63 identical items = Selling Price of 54 items

Formula Used:

Profit Percent $$= \frac{Profit}{CP} \times 100$$​​

Solution:

According to question:

63CP = 54SP

​$$\frac{CP}{SP} = \frac{54}{63}$$​​

If CP = 54 then SP = 63

Then profit = 63-54 = 9

Profit Percent =$$\frac{9}{54} \times 100 = \frac{50}{3}\% = 16\frac{2}{3}\% Gain$$​​
