- If A is not 1, then C is not 3.
- If B is either 2 or 1, then A is 3.
- If C is not 2, then A cannot be 3.
- If C is not 1, then A is not 3.
- If C is 3, then B is not 1 or 2.
- If B is 3, then A is not 2.

Match ABC to 123
You need to match A, B and C to the numbers 1, 2 and 3. But you are given some peculiar information by which to determine how to match them up.

I guess following is the answer:
ReplyDeleteA=1
B=3
C=2

Correct. A is 1, B is 3, and C is 2. Given statements three and four, A cannot be 3, because it must be either not 1 or not 2. Given statement two, and that A cannot be 3, B must be 3. Given statement six, A must be one, because B is 3 and A is therefore not 3 or 2. That leaves 2 for C.
ReplyDeleteA=1
ReplyDeleteB=3
C=2
Random guess...
A is first C is second and B is third! Simply a matter of narrowing down. Nothing a paper and pen can't solve, and a few minutes, ok a few more then a few minutes but I got the answer in the end! I think :)
ReplyDeleteWith only six possibilities, it should be fairly quick to write them down and eliminate them all (except for the true answer), right?
ReplyDeleteThen why did it take me so long! ;-)
You had it right: A-1, B-3, C-2
so the first clue if A=1 then C cannot = 3 means that C=2 and B=3
ReplyDeleteI think that it was a give away from the first response! :)
Thanks a lot for posting
