1. Buffet dinner at a restaurant costs Tk 35.50 . If the sales tax was more than 10 percent but less than 15 percent of the pre-tax cost of the dinner, then the total amount paid must have been between--
- A. Tk 40 & Tk 42
- B. Tk 40 & Tk 42
- C. Tk 40 & Tk 42
- D. Tk 40 & Tk 42
Answer: Option B
Explanation:
The minimum value of 10% including tax = 35.50 + 3.55 = 39.05
and the maximum value of 15% including tax = 35.50 + 5.325 = 40.825
So, the total amount will be paid Tk. 39 and tk. 41
