Question

Applied to a bill of ₹600, the difference between a single discount of 25% and two successive discounts of 10% and 15% is:

• A. ₹1.5
• B. ₹11
• C. ₹10
• D. ₹9

Answer 1

Answer:

D. ₹9

Bill amount = ₹600

Single discount of 25%

$25\% \text{ of } 600 = 150$

Price after discount:
600 - 150 = 450
Successive discounts of 10% and 15%

First 10% discount:
$10\% \text{ of } 600 = 60 \Rightarrow 600 - 60 = 540$

Then 15% discount on 540:
$15\% \text{ of } 540 = 81 \Rightarrow 540 - 81 = 459$

Difference

459 - 450 = ₹9
