Description : Can you divide the watch face with 2 straight lines so that the sums of the sums of the numbers in each part are equal? -Riddles

Last Answer : The sum of the numbers on the watch face is 78. If the two lines cross, there must be 4 equal parts, but 78 is not divisible by 4. Then the lines do not cross, giving three parts with the sum of 26 each. ... pairs on the face that add to 13(12+1,11+2, and so far) the answer will be easy to find.
