The cost price of a particular amount of articles is same as the number of articles. Selling price of the articles comes out to be 20. Over the whole transaction 25% is gained. What is X?Options20171618

The question seems to be incomplete as it does not specify what 'X' refers to. However, I can help you understand how to calculate the cost price and the selling price based on the information given.

1. It is given that the cost price of a particular amount of articles is the same as the number of articles. Let's denote the number of articles (and also the cost price) as 'N'.

2. The selling price of the articles is given as 20.

3. It is also given that a 25% gain is made over the whole transaction. This means that the selling price is 125% of the cost price.

We can set up the equation as follows:

1.25 * N = 20

Solving for N, we get N = 20 / 1.25 = 16

So, the number of articles (and also the cost price) is 16. If 'X' refers to the number of articles or the cost price, then X = 16.
