Solutions
For option a:
Selling price of article = 1500 + 300 = Rs. 1800
Mark-up price of article = 1500 x 1.6 = Rs. 2400
Therefore, selling price of article after discount = 2400 – 600 = Rs. 1800
So, option a can be the answer
For option b:
Selling price of article = 1500 + 300 = Rs. 1800
Mark-up price of article = 1500 x 1.5 = Rs. 2250
Therefore, selling price of article after discount = 2250 – 450 = Rs. 1800
So, option b can be the answer
For option c:
Selling price of article = 1500 + 300 = Rs. 1800
Mark-up price of article = 1500 x 1.4 = Rs. 2100
Therefore, selling price of article after discount = 2100 – 300 = Rs. 1800
So, option c can be the answer
So option (e) is the correct answer.
