Correct Answer - Option 3 : Loss 22%
Given:
Discount = 40%
Formula used:
SP = MP × (100 - D%)/100
Loss = SP - CP
Loss % = (Loss/CP) × 100
Calculation:
Let the cost price of the article be 100x
So, marked price of article = 130x
After 40% discount on the marked price
Selling Price = 130x - 40% of 130x = 130x - 52x = 78x
So, there is loss
Loss = 100x - 78x = 22x
Loss % = (22x/100x) × 100 = 22%
∴ Shopkeeper has a loss of 22%.
