Christmas Challenge 2018 Solutions

What was the solution to the 20 Presents to be divided up into 5 Santa sacks with each having equal weight? It was the first question on original challenge.

Hi Vicky

There were two potential solutions to the Santa’s Sack puzzle – you can find all of the answers here:

Thanks

The answer to the pyramid question (the final one – how many crackers are required) is 7 boxes with 6 left over, as the pyramid adds up to 78, not 66.

The solution to Puzzle 4 – Santa and the Twelve Elves in the ‘Deputy First Minister’s Maths Christmas Holiday Challenge 2018’ may contain an error. My son Jack worked out the total number of crackers required to be 78 therefore 7 boxes rather than 66 crackers and 6 boxes. Can you confirm if there is indeed and error in the solution or if he is incorrect? Thanks

Hi Ben, thanks for raising this with us – the solutions on the blog have now been updated accordingly.

In the cracker question:

“12+11+10+9+8+7+6+5+4+3+2+1=66”

should read:

12+11+10+9+8+7+6+5+4+3+2+1=78

So answer is 7 boxes with 6 left over

Hi John, thanks for raising this with us – the solutions on the blog have now been updated accordingly.

Are the answers to puzzle 3 and 4 correct?

For number 3 the question was how many MORE houses are required which would be 420 minus the existing 90 so the answer 330.

And for number 4 the total number of crackers is 78 so 7 boxes of crackers with 6 left over.

Hi there, thanks for raising this with us – the solutions on the blog have now been updated accordingly.
