Question

Nut B fits on Bolt B. Nut A fits on Bolt C, but does not fit on Bolt A. Bolts B and A are exactly the same. Given the scenario, will nut A fit on Bolt B?

Answer 1

Nut B -> Bolt B
Nut A -> Bolt C, but NOT Bolt A
Bolt B is also the same as Bolt A, so Bolt B = Bolt A
Then, Nut B -> Bolt A.
Remember that Nut A didn't fit on Bolt A, and Bolt A is the same as Bolt B. 

So, Nut A will NOT fit on Bolt B.
