Question 261179
<ol><li>If the mean of the five numbers is 5, then the sum of the five numbers must be 25.</li><li>If the median of the five numbers is 6, then two of the five numbers must be lower than 6 and the other two numbers must be larger than 6.</li><li>If the mode is 7 then there must be more 7's than any other number. Since there are two numbers above 6 (see #2), they both must be 7's!</li><li>So four of the five numbers are: 5, 6, 7 and 7. These four numbers add up to 25. Since the five numbers must add up to 25 (see #1), then the fifth number must be 0!</li></ol>
