A 75 mg dose is required. Each tablet is 25 mg. How many tablets are needed?

• A. 3 tablets
• B. 4 tablets
• C. 2 tablets
• D. 1 tablet

Answer: (A)

To figure out how many tablets are needed, divide the total dose by the amount each tablet supplies. Here, 75 mg is required and one tablet provides 25 mg. 75 ÷ 25 = 3, so three tablets are needed to reach the 75 mg dose. This matches the target exactly because 3 × 25 mg equals 75 mg. Using fewer would underdose (two tablets give 50 mg), and using more would overdose (four tablets give 100 mg). The division works cleanly here, so no rounding is required.
