Correct Answer - Option 1 : 25%
Given:
Selling price of 12 articles = Cost price of 9 articles
Formula Used:
Loss = Cost price - Selling price
Loss% = (Loss/Cost price) × 100
Calculation:
Let assume that cost price of 1 article = x
So, cost price of 9 articles = 9x
Selling price of 1 article = y
So, selling price of 12 articles = 12y
According to question
⇒ 9x = 12y
⇒ x/y = 12/9
⇒ x/y = 4/3
Loss = Cost price - Selling price
⇒ Loss = 4unit - 3 unit = 1 unit
Loss% = (Loss/Cost price) × 100
⇒ Loss% = 1/4 × 100
⇒ Loss% = 25%
∴ Loss% is 25%
The correct option is 1 i.e. 25%
