Week 1 - Problem 2

The face of a clock is cracked into 4 pieces. The sums within the parts are consecutive numbers. Provided there is only one possible way to crack it, the face would look like:


  1. it is a pretty easy problem. All that you have to do is find the sums of each section of each clock and circle the one that has all its numbers consecutive. a quicker way to do it is that if you see the sum of one section is 14 and another is 18 then you know that in not the answer. also, E is defenetly not the answer because it is only devided into 3 sections instead of 4. Or if you see that in 1 section the numbers are 12, 11, and 10 and in another section the numbers are 1, 2, 3, and 4 then that is not the answer either
