An article is sold at 15% discount. If the marked price is Rs. 500, what is the selling price?
Rs. 425
Rs. 450
Rs. 475
Rs. 400
Rs. 425
Calculate 10% of 500 (50) and 5% of 500 (25). Subtract the total discount (50 + 25 = 75) from the original 500 to get 425.
Marked Price (MP) = Rs. 500, Discount Percentage = 15%.
SP=MP├Ч(1тИТ100Discount%тАЛ)
Calculate 10% of 500 (50) and 5% of 500 (25). Subtract the total discount (50 + 25 = 75) from the original 500 to get 425.
Students often mistakenly calculate 15% of the selling price instead of the marked price, or add the discount instead of subtracting it.
Identify Given Values
Identify the marked price (MP) as 500 and the discount rate as 15%.
MP=500,D=15%
Calculate Discount Amount
Calculate the actual discount value by finding 15% of 500: Discount=500├Ч0.15.
Discount=75
Calculate Selling Price
Subtract the discount amount from the marked price to find the selling price (SP).
SP=500тИТ75=425
A is correct because subtracting the discount of Rs. 75 from the marked price of Rs. 500 results in Rs. 425.
