Final answer:
To calculate the percentage of discount, subtract the selling price from the marked price to find the discount amount and then divide it by the marked price and multiply by 100. The discount offered on the article is 20%.
Step-by-step explanation:
To find the percentage of discount, we need to calculate the discount amount first.
Discount = Marked Price - Selling Price = Rs 1350 - Rs 1080 = Rs 270
Now, we can calculate the percentage of discount:
% discount = (Discount / Marked Price) * 100 = (270 / 1350) * 100 = 20%
First, we determine the discount amount by subtracting the selling price from the marked price: Rs 1350 - Rs 1080 = Rs 270.
Next, we calculate the discount percentage: (Rs 270 / Rs 1350) × 100 = 20%.
Therefore, the percentage of discount offered on the article is 20%.
