Divide the face of the clock into three parts with two lines

Divide the face of the clock into three parts with two lines so that the sum of the numbers in the three parts are equal

Solution

A clock has twelve numbers - 1 to 12. Sum of these twelve numbers is 78.

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

we need to divide face of the clock drawing two lines that will divide face of the clock in three parts such that sum of numbers in each parts will be equal.

Therefore sum of number in each part should be 78/3 = 26.

This can be achieved by dividing the clock in three parts by two horizontal lines that divide the clock in three parts.

The top part will contain the numbers 1, 2, 11 and 12.

The second part in middle will contain numbers 3, 4, 9 and 10.

The lowest part will contain the numbers 5, 6, 7 and 8.
