Question: 244
5. Which of the following is a multiple of both 3 and 5 ?
- A. 10
- B. 20
- C. 25
- D. 45
Correct Answer: D
Explanation:
D The question is essentially asking for a number that is divisible by both 3 and 5. 10, 20, and 25 are all divisible by 5, but not by 3. Eliminate (A), (B), and (C). 45 ÷ 3 = 15 and 45 ÷ 5 = 9, so 45 is divisible by both 3 and 5. The correct answer is (D). Remember, you can also use the divisibility rules for 3 and 5 to help with this question! All the numbers end in either 5 or 0, so they are all divisible by 5. However, only (D) has digits that add up to a number divisible by 3.
