Answer 9

The total of the given scores = 12 + 34 + 9 = 55
The smallest possible total weekly score is 3 + 2 + 1 = 6
The factors of 55 are 5 and 11, therefore the number of weeks to achieve the given scores must be 5, the reason being that 5 is too small to be a total weekly score.
When the total scores for the additional weeks are added to 55 the new total must have 11 as a factor and must also have 3 as a factor. Can you find the new toal that satisfies all conditions?

Answer 10

Try 66 as a new total score, since both 3 and 11 are factors. In this case the total score of each of the 3 contestants would be 22. However at the end of week 5 Ben's total score was 34. Therefore the new total must be higher than 66.
