I'm thinking of a number.
- if it is not a multiple of 4, then it is between 60 and 69
- if it is a multiple of 3 it is between 50 and 59
- if it is not a multiple of 6 it is between 70 and 79.
What is the number?
SOLUTION: 60
HOW?:
Since 3 and 6 are the same, 3 could be right and 6 then would be right. Thus, it might be a multiple of 4, and the only way they could be the same is if it's 60. So it's 60.
