Answer 2

The gain percent made by the man by selling an article of Rs.20 at Rs. 40 is 100%.

Given :

The Buying price of an article = Rs. 20

The Selling price of the article = Rs. 40

To Find :

The gain percent in selling the article

Solution :

The price at which any item is brought or made is called its Cost Price i.e. CP. And then the price at which it is finally sold after making a loss or profit is called Selling Price i.e. SP.

Here, CP = Rs. 20

SP = Rs. 40

Firstly, we need to calculate the profit : ( as SP > CP )

                       Profit. $= SP - CP$

                                  $= 40 - 20$

                                  $= 20$

Then for calculating the Gain Percent, we need to find what percent of the cost price is the actual profit made. i.e.

               Gain Percent = $( Profit / CP ) * 100$

                                      $= (20/20) * 100$

                                      $= 100$

Hence, the man makes a 100% gain profit by selling the article.
