Let the cost price of 1 article be $1. Therefore, cost price of 20 articles = 20 * 1 =$20

The selling price of 25 articles = cost price of 20 articles = $20. Now, we know the selling price of 25 articles. Let us find the cost price of 25 articles. Cost price of 25 articles = 25 * 1 =$25.

Therefore, profit made on sale of 25 articles = Selling price of 25 articles - cost price of 25 articles

= 20 - 25 = -$5. As the profit is in the negative, the merchant has made a loss of$5.

Therefore, % loss = loss/cp * 100
% loss = -5/25 * 100 = 20% loss.

Let cost price of one article be c and selling price of one article be s.
We need to find profit/loss% which is equal to ((s-c)/c) x 100 = (s/c - 1) x 100

Given that 20c = 25s. Then s/c = 4/5
Profit% = (4/5 - 1) x 100 = -20%

Note: It is preferable to use as few variables as possible but in situations where cp of n articles = sp of m articles, it is better to use different variables for clarity.
