The marked price of an article is Rs 1500. A shopkeeper sells it by giving 20% discount on its marked price. If the cost price of the article is Rs 991. then his profit (in RS) is:
SP = MP × [(100 – Discount%)/100] SP = 1500 × [(100 – 20%)/100] => SP = 1500 × [80/100] => SP = 1200 Now, Profit = SP - CP Profit = 1200 – 991 Profit = Rs. 209
