Question

If the cost price of an article is 10 percent of its selling price, then what is the profit percent ?
1. 950 percent
2. 750 percent
3. 900 percent
4. 800 percent

Answer 1

Correct Answer - Option 3 : 900 percent

Given 

Cost price = 10% of selling price 

Formula used 

Profit% = (profit/cp) × 100 

Calculation

Cost price = (10/100) × selling price 

Cost price : Selling price = 1 : 10 

Profit = 10x - x = 9x 

Profit% = (9x/x) × = 900% 

∴ The profit percent is 900%
