There are multiple ways of arranging numbers 1-12 into 3 sets such that sum of each set is equal. On could be : 1-6-7-12, 2-5-8-11, 3-4-9-10.

1) Sum of numbers from 1-12 is 78.

2) If we have to divide them into 3 sets with equal sum then sum of each set would be 78/3 = 26.

3) Hence, another possible combination would be 1-2-11-12, 3-4-9-10, 5-6-7-8

It is proved that the sum of the three sides are equal to each other, it is 26.

Given:

Divide the clock face into three equal parts exactly.

Therefore the sum of the numbers in the 3 equal parts should be same

Solution:

The clock has numbers from 1 to 12

It has to be divided into three parts such that their sum is equal.

They are,

i) 11 + 12 + 1 + 2

ii) 3 + 4 + 9 + 10

iii) 5 + 6 + 7 + 8

And it is proved that,

The sum of the three sides are equal to each other, it is 26.

      11 + 12 + 1 + 2 = 3 + 4 + 9 + 10 = 5 + 6 + 7 + 8 = 26
