1) Clearly not sufficient.

2) Gives me the following equations $$A=3B, B=A-1$$. On solving I get the number of cakes for A as $$3/2$$

Doubt Since the number of cakes has to be an integer, and 2) gives me a non-integer answer, should the answer be E or B?

PS: This is a self made question, made it to clarify this doubt, can such questions show up on the GMAT?

No, you won't get such question on the tests. If a variable must be an integer then it will be an integer. So, the answer to your question is none of the options, it's flawed by GMAT standards.

Okay! Thanks
