Number Puzzle: Who could I be?
We have six statements about a number, and we know that exactly 1 is false.
- I am greater than 50
- I am a multiple of 7
- I am a perfect square
- I am a 3-digit number
- I am less than 500
- I am a multiple of 17
Are there any numbers that fit? How many? And if they exist, what are they?
Unrelated, interesting note: Nice factoring techniques for solving problems such as
Find n such that n(n+16) is a perfect square
