अक्सर पूछे जाने वाले प्रश्न
How do you find the original price before tax or markup?
Divide the final price by (1 + (Percentage Rate / 100)). For discounts, divide by (1 - (Discount % / 100)).
Why can you not simply subtract the percentage from the final price?
Because the percentage was originally applied to the smaller starting amount, not the larger final amount.
