A customer could not decide between a discount of 40% or two successive discounts of 25% and 15% to buy a certain article. What is the difference between both the discounts?

A3.25%

B2.75%

C2.25%

D3.75%

Answer:

D. 3.75%

Read Explanation:

Let the marked price be ₹100 (for easy calculation).

Case 1: Single discount of 40%

Discount=40\text{Discount} = 40% \text{ of } 100 = 40
Selling Price=10040=60\text{Selling Price} = 100 - 40 = 60

Case 2: Two successive discounts of 25% and 15%

First discount:
2525% \text{ of } 100 = 25
Price after first discount:
10025=75100 - 25 = 75
Second discount:
1515% \text{ of } 75 = 11.25
Total discount:
25+11.25=36.2525 + 11.25 = 36.25
Difference between the discounts:

4036.25=3.7540 - 36.25 = 3.75

The difference between both discounts is 3.75%.
