Question

A sales man offers the following scheme discount on the sale of pencils in his shop: 'Buy 20 and get 5 free'. What is the percentage of his scheme discount?

• A. 15%
• B. 10%
• C. 20%
• D. 25%

Answer 1

Answer:

C. 20%

Scheme: Buy 20 and get 5 free

So total pencils received = 20 + 5 = 25
But paid for = 20

Discount in terms of value

Free pencils = 5 out of 25 total

Percentage discount

$\text{Discount \%} = \frac{5}{25} \times 100$

= 20%

Final Answer: 20%
