The selling price of 30 articles is equal to the purchase price of 25 articles. Find the percentage of profit or loss.

A18% profit

B16 and two-thirds percent loss ✓ Correct

C18% loss

D16 and two-thirds percent profit

Correct answer: (B) 16 and two-thirds percent loss

Explanation

There is a loss of 16 and two-thirds percent.

Let the cost price of each article be 1, so 25 articles cost 25.

The selling price of 30 articles equals this 25.

Selling price per article = 25/30 = 5/6.

Loss per article = 1 - 5/6 = 1/6.

Loss percent = (1/6) x 100 = 16 and two-thirds percent.
