Question 1
<p>Five racing drivers, Alan, Bob, Chris, Don, and Eugene, enter into a contest that consists of 6 races. The results of all six races are listed below:</p><ul style='list-style-type: disc; list-style-position: outside;'><li>Bob always finishes ahead of Chris.</li><li>Alan finishes either first or last.</li><li>Eugene finishes either first or last.</li><li>There are no ties in any race.</li><li>Every driver finishes each race.</li></ul><p>In each race, two points are awarded for a fifth place finish, four points for fourth, six points for third, eight points for second, and ten points for first.</p><br><br>If Eugene's total for the six races is 36 points, which of the following must be true?
- Bob's total is more than 36 points.
- Chris's total is more than 36 points.
- Alan's total is 36 points.
- Don's total is less than 36 points.
- Don's total is 36 points.
Answer: Alan's total is 36 points.
Explanation: If Eugene has 36 points, than he must have 3 first place finishes and 3 last place finishes, because he finishes first or last in every race. Therefore, Alan must also have 3 first place finishes and 3 last place finishes for a total of 36 points. Some of the other options may be true, but none of them are required.
Question 2
<p>Five racing drivers, Alan, Bob, Chris, Don, and Eugene, enter into a contest that consists of 6 races.
