Final answer:
Upon calculating and checking each option, none of the entries correctly represent a product's marked price, discount price, and discount percentage. The calculations for each option do not result in the discount prices provided in the question, indicating an issue with the options.
Step-by-step explanation:
The question asks which entry correctly represents a product's marked price, discount price, and discount percentage. To find this out, we need to check if the discount price is the result of applying the discount percentage to the marked price. To calculate the discount price from the marked price and discount percentage, use the formula: discount price = marked price - (marked price × discount percentage).
- a) 125, 100, 15% - To check: 125 - (125 × 15%) = 125 - 18.75 = 106.25 (This does not match the discount price of 100.)
- b) 70, 21, 15% - To check: 70 - (70 × 15%) = 70 - 10.5 = 59.5 (This does not match the discount price of 21.)
- c) 240, 64, 22% - To check: 240 - (240 × 22%) = 240 - 52.8 = 187.2 (This does not match the discount price of 64.)
- d) 351, 155, 31% - To check: 351 - (351 × 31%) = 351 - 108.81 = 242.19 (This again does not match the discount price of 155.)
Upon checking each option, none of the entries correctly represent a product's marked price, discount price, and discount percentage based on the calculation. Therefore, there seems to be a mistake as none of the options given are accurate.
