Solution
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.
- Sum of numbers from 1-12 is 78.
- If we have to divide them into 3 sets with equal sum then sum of each set would be `78/3` = 26.
- Hence, another possible combination would be 1-2-11-12, 3-4-9-10, 5-6-7-8
