Also, there is a question in module 45- Q 14.

The question is In calculating the breakeven point for a multi-product company, which of the following assumptions are commonly made when variable costing is used??

I. Sales volume equals production volume

II. Variable costs are constant per unit

III. A given sales mix is maintained for all volume changes.

a. I and II

b. I and III

c. II and III

d, I, II and III

The answer given by Wiley is C. BUT the answer given by Gleim is D.

Ha...the same questions with different answers ...which one should we follow??? I go with Gleim...what u guys think?? Help!

I used Wiley for BEC as well, I remember I picked D and did not get why Wiley shows C as a correct answer. I believe D is correct cause condition I is a must.
