Answer 1

cost price of 1 article be 10rs

therefore cost price of 12 articles us 120rs

but 120 is selling price of 20 articles

therefore selling price of 1 article is 6 rs

therefore 40 % loss

Answer 2

Step-by-step explanation:

Let the cost price of 1 article be 1.

Therefore, cost price of 12articles = 12 * 1 = 12

The selling price of 20articles = cost price of 12articles = 12

Now, we know the selling price of 20 articles. Let us find the cost price of 12 articles.

Cost price of 20 articles = 20* 1 = 20

Therefore, profit made on sale of 20 articles = Selling price of 20 articles - cost price of 20articles

= 20 - 12 = 8

Therefore, % profit= profit/cp * 100

% profit= 8/20 * 100 = 40% profit
