On a Tuesday, an accountant has exactly seven bills -- numbered 1 through 7 -- to pay by Thursday of the same week. The accountant will pay each bill only once according to the following rules:

Either three or four of the seven bills must be paid on Wednesday, the rest on Thursday.
Bill 1 cannot be paid on the same day as bill 5.
Bill 2 must be paid on Thursday.
Bill 4 must be paid on the same day as bill 7.
If bill 6 is paid on Wednesday, bill 7 must be paid on Thursday.

Which one of the following is a complete and accurate list of the bills any one of which could be among the bills paid on Wednesday?

  1. 3, 5, and 6
  2. 1,3,4,6, and 7
  3. 1,3,4, 5, 6, and 7
  4. 2, 3, 4, 5, 6, and 7
  5. 1,2,3,4, 5, 6, and 7

Answer(s): C

Explanation:

We need to find the choice that lists all of the bills that could possibly be paid on Wednesday, and none of the bills that must be paid on Thursday. Choices [2, 3, 4, 5, 6, and 7] and [1,2,3,4, 5, 6, and 7] can be eliminated, because they both list bill 2, which must be paid on Thursday (Rule 3).



On a Tuesday, an accountant has exactly seven bills -- numbered 1 through 7 -- to pay by Thursday of the same week. The accountant will pay each bill only once according to the following rules:

Either three or four of the seven bills must be paid on Wednesday, the rest on Thursday.
Bill 1 cannot be paid on the same day as bill 5.
Bill 2 must be paid on Thursday.
Bill 4 must be paid on the same day as bill 7.
If bill 6 is paid on Wednesday, bill 7 must be paid on Thursday.

If bill 2 and bill 6 are paid on different days from each other, which one of the following must be true?

  1. Exactly three bills are paid on Wednesday.
  2. Exactly three bills are paid on Thursday.
  3. Bill 1 is paid on the same day as bill 4.
  4. Bill 2 is paid on the same day as bill 3.
  5. Bill 5 is paid on the same day as bill

Answer(s): A

Explanation:

We know that bill 2 is paid on Thursday, so, bill 6 must therefore be paid on Wednesday.
Rule 5 then dictates that the accountant pay bill 7 on Thursday, along with bill 4 (Rule 4).
We now have four bills on Thursday (2, 7, 4, and 1/5), so the remaining bill, 3, must be paid on Wednesday.



On a Tuesday, an accountant has exactly seven bills -- numbered 1 through 7 -- to pay by Thursday of the same week. The accountant will pay each bill only once according to the following rules:

Either three or four of the seven bills must be paid on Wednesday, the rest on Thursday.
Bill 1 cannot be paid on the same day as bill 5.
Bill 2 must be paid on Thursday.
Bill 4 must be paid on the same day as bill 7.
If bill 6 is paid on Wednesday, bill 7 must be paid on Thursday.

If bill 6 is paid on Wednesday, which one of the following bills must also be paid on Wednesday?

  1. 1
  2. 3
  3. 4
  4. 5
  5. 7

Answer(s): B

Explanation:

Again, we have bill 6 on Wednesday. You can use the work from the previous question; it's the same sketch.
Choice [3], which has bill 3 paid on Wednesday, is correct.

Either three or four of the seven bills must be paid on Wednesday, the rest on Thursday.
Bill 1 cannot be paid on the same day as bill 5.
Bill 2 must be paid on Thursday.
Bill 4 must be paid on the same day as bill 7.
If bill 6 is paid on Wednesday, bill 7 must be paid on Thursday.

If bill 4 is paid on Thursday, which one of the following is a pair of bills that could also be paid on Thursday?

  1. 1 and 5
  2. l and 7
  3. 3 and 5
  4. 3 and 6
  5. 6 and 7

Answer(s): B

Explanation:

If bill 4 is paid on Thursday, then so is bill 7 (Rule 4). Again, that's four bills on Thursday (2, 7, 4, and 1/5), so the rest (6, 3, and 1/5) must be on Wednesday. Now we need a pair of bills that could be paid on Thursday.

Answer(s): C

Explanation:

This question provides us with no new information, so unfortunately there's nothing for us to do but test out each choice. The choices are in if/then form, so this could take some time.
