The cost price of an item is one-fourth of its selling price. What is the gain or loss percentage on that item?

Correct option is A

Given:

Cost Price of an item = one-fourth of Selling Price

Formula Used:

Profit = Selling Price - Cost Price

Profit Percentage $$= \frac{Profit}{Cost\ Price} \times 100$$​​

Solution:

Let the selling Price be 4x

Then Cost Price =$$\frac{1}{4} of 4x = x$$​​

Profit = 4x -x = 3x

Profit Percentage =$$\frac{3x}{x} \times 100 = 300\%$$​​
