Answer:
Original Sale Price = $6000
Explanation:
Lets say that the original Sale price is 100%. When the first discount is offered, the car is discounted by 10% and offered for 90% of the original price.
The second discount is offered as 20% off from the discounted sale price. Thus the car is now offered at,
Price after Second Discount = 90% * (1 - 20%) = 72% of the original price
Now the final discount is offered as further 25% off from the Second Discounted price which is already 72% of the original price. Thus the price after final discount will be,
Price after final discount = 72% * (1 - 25%) = 54% of the original price
We know the price after final discount is 54% of the original price and we are provided the amount as 3240. Thus if 54% of original price is 3240, then the original price will be,
Original Sale Price = 3240 * 100%/54%
Original Sale Price = $6000
