Time Will Tell
Q Picture a regular (analog) clockface ? with the numerals 1 to 12 correctly positioned.

Where would you draw a straight line to split the clockface in half in such a way that the sum of the numbers on one side of the line will equal the sum of the numbers on the other side of the line?

A Draw a straight line that begins on the left side of the clockface between 9 and 10 and cuts across the clockface to the right side between 3 and 4. The sum of the numbers above the line equals 39, and the sum of the numbers below the line equals 39.
