Sam owns 70 percent of the stock of club corporation. unrelated individuals own the remaining 30 percent. for a stock redemption of sam's stock to be treated as an exchange under the "substantially disproportionate" test, what percentage of club stock must sam own after the redemption?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
