The ratio of selling price of an article to the cost price of the article is 9 : 11. What is the loss percentage?
Show answer & explanation
Correct answer: A
Explanation
Given:
SP : CP = 9 : 11
According to the formula:
Loss % = [(CP − SP) / CP] × 100
Let SP = 9 and CP = 11
Loss = 11 − 9 = 2
Loss % = (2/11) × 100 = 18.18%
