Question 21
HardOriginal questionWhich diagram best represents the relationship among Odd numbers, Multiples of 6 and Multiples of 3?
Show the answer and explanation
Correct answer: D
Explanation
Every multiple of 6 is a multiple of 3: Multiples of 6 sits inside Multiples of 3.
9 is odd and a multiple of 3; 5 is odd but not a multiple of 3; 6 is a multiple of 3 but not odd: Odd numbers overlaps Multiples of 3.
Every multiple of 6 is even, so no odd number is a multiple of 6: Odd numbers misses the small circle.
So a small circle inside a larger one, with a third circle overlapping the larger circle only.
Worth noting
Two separate circles inside Multiples of 3 would put every odd number inside Multiples of 3, but 5 and 7 are odd and not multiples of 3.
