Question

An online retailer sells a product of Rs. 13000 at a price of Rs. 7800 after two successive discounts (festive discount and coupon discount). If the first discount is 25% then what is the percentage of coupon discount.

• A. 20 %
• B. 17 %
• C. 24 %
• D. 15 %

Hint:

Only one of these poisons is specifically linked to cherry-red blood coloration.

Answer 1

The Correct Option is A

Starting from the original price of Rs. 13,000, the first (festive) discount of 25% brings it down to \(13000 \times 0.75 = 9750\). This reduced price is then cut further by the coupon discount, all the way down to the final selling price of Rs. 7,800, so the coupon discount amount is \(9750 - 7800 = 1950\).
Expressed as a percentage of the price it was applied to, Rs. 9,750, the coupon discount rate works out to \(\dfrac{1950}{9750} \times 100 = 20\%\).
That matches option 1.
