40 percent of the cost price of an article is equal to the 50 percent of its selling price. What is the loss percentage?
Show answer & explanation
Correct answer: A
Explanation
Let Cost Price = CP
Selling Price = SP
40% of CP = 50% of SP
40/100 CP = 50/100 SP
SP/CP = 40/50 = 4/5
Loss % = 1/5 × 100 = 20%
