Question : The marked price of an article is INR 28,000. It can be sold in one of the following ways: Way A: A single discount of 24%. Way B: Two successive discounts of 16% and 10%. Which way will have the lowest selling price and what will be the value of it?
Option 1: Way A, INR 21,168
Option 2: Way B, INR 21,280
Option 3: Way A, INR 21,280
Option 4: Way B, INR 21,168
Correct Answer: Way B, INR 21,168
Solution : Given: The marked price of an article is INR 28,000. Use the formula, $SP=(1-\frac{d_1}{100})\times (1-\frac{d_2}{100})\times MP$ where $SP, d_1, d_2$ and $MP$ are the selling price, the discount percentages, and the marked price. For the Way A, $SP=1–\frac{24}{100}\times 28000$ ⇒ $SP=\frac{100–24}{100}\times 28000$
