Not SixThese brain teasers rely on your ability to recognize groups of common attributes. For each of these puzzles you'll need to figure out why the words or letters are grouped as they are. Sometimes you will be asked to pick the odd-one-out or to place a new word into the correct group.
What are the groups and why is the number 6 not included?
HintIt has nothing to do with even or odd, but all primes are in the same group
AnswerAll numbers in group A are greater than the sum of all numbers they are divisible by (except for themselves). I.e, 1+2+5<10. In group B, all numbers are less than the sum of all numbers they are divisible by (except for themselves). I.e, 1+2+3+4+6>12. The number 6 is omitted because all numbers it is divisible by add up to 6. 1+2+3=6
