This was the hardest question, I found. It was the only one where I found drawings useful (besides the main drawing).
This question asks about Tuesday, but the day doesn’t matter. This would be the exact same question if it was talking about any other day with transfer. On this game the days are just a distraction.
First, you can eliminate a couple answers. C is wrong because J can’t transfer to M (rule 1).
D is wrong because K and L pass back and forth between them. This leaves J and M to transfer between each other. But J can’t transfer to M (rule 1), so this doesn’t work.
For the other three answers, I had to make drawings of what was happening. Note that M always transfers to J (we saw this in question 20) so I drew that as well.
I’ll repeat that last line because it’s important. M always has to transfer to J. We saw this in the setup. So all the drawings include this transfer.
Note also that everyone must send and receive a transfer. Two answers are wrong because they leave one employee without a transfer partner.
A has transfers from J to K, K to M, and M to J:
This left L without anyone to transfer with.
B has transfers from J to L, L to M and M to J:
This leaves K without anyone to transfer with.
E is CORRECT. It has transfers from K to L and L to M. There’s also the routine transfer from M to J:
Finally, I drew a transfer from J to K, because J hadn’t transferred and K hadn’t received. That was just to prove to myself that this answer allowed all four people to make and receive transfer.
So E doesn’t violate any rules and it has everyone making a transfer and everyone receiving a transfer.
