1. 10%
2. 12%
3. 14%
4. 16%

Answer 1

Correct Answer - Option 1 : 10%

Given:

Cost price ∶ Selling price = 10 ∶ 9

Formula Used:

Loss = Cost Price - Selling Price

Loss% = Loss/Cost price × 100

Calculation:

Let assume cost price be = 10x

Selling price = 9x

⇒ Loss = 10x - 9x = x 

According to the formula used

⇒ Loss% = (x/10x) ×100 = 10%

∴ The correct option is 1 i.e.10%
