Q: Can you take the clock face below, and cut it into four pieces such that the numerals on each part add up to the same number?
A: The key is to turn the number XI upside down to a IX or:
turn the IX upside down to a XI
The numbers 1-12 add up to 78 which is not divisible by 4
Replace 11 with a 9 and the numbers now add up to 76 which is divisible by 4
and/or replace the 9 with an 11 and now the numbers add up to 80 which is also divisible by 4
