Correct Answer - Option 3 : 15%
Given:
A discount of Rs. 120 is given on an article whose marked price is Rs. 800
Formula Used:
Discount is always calculated on marked price(MP)
Discount% = (Discount/MP) × 100
Calculation:
Discount = Rs. 120, MP = Rs. 800
Discount% = (120/800) × 100
= 15%
∴ Discount% is 15%
