A is offering Z to B for Y. B counters and offers C. A refuses and again offers Z to B for Y. B then offers C to X for D. X accepts. A later trades Z to B for? Y? I seriously doubt it. It's simple logic, really.
What?
Tell me then, what offers did Hart turn down for JUp?
I thought I made it pretty clear. He turned down C for Z.
Bearing in mind that some deals are in place before they are announced, here is all the information you need to figure out C, D, X, and Y (if you need help figuring out Z, A, or B, this is a pointless conversation).
