• B. 33%
• C. 30%
• D. 20%

Answer 1

Answer:

A. 25%

Offer: Buy 15 bulbs, get 5 free

Total bulbs received

15 + 5 = 20
Effective cost

Customer pays for 15 bulbs, but gets 20 bulbs

Discount

Free bulbs = 5 out of 20

$\text{Discount \%} = \frac{5}{20} \times 100 = 25\%$

Final Answer:

25% discount
