howdy! hope you are having a good day!
to find the marked price (the original price) of the TV set, you can use the formula:
Marked Price = Selling Price / (1 - Discount Percentage)
in this case, the selling price is Rs 11,500, and the discount is 8%, which can be expressed as a decimal by dividing by 100 (8% = 0.08).
plug these values into the formula:
Marked Price = 11,500 / (1 - 0.08)
Marked Price = 11,500 / 0.92
Marked Price ≈ Rs 12,500
the marked price of the TV set is 12,500.
