The sum of the numbers 1 to 12 = (1 + 12)(2 + 11)(3 + 10) ... (6 + 7). That's 6 sets of 13 = 78.

Divide that by 3 and you get an average of 26.

So you need each section to add to 25, 26 and 27 respectively.

I assume you have to keep consecutive numbers together... one way to do that is:

3, 4, 5, 6, 7 = 25
8, 9, 10 = 27
11, 12, 1, 2 = 26

The sum of the even numbers in the group where 5 is present {3, 4, 5, 6, 7} is 4 + 6 = 10.

The answer is B) 10.

Ans:10

in the pieces, the numbers will be distributed in the following way
{3,4,5,6,7} [sum. 25]
{8,9,10} [sum. 27]
{11,12,1,2} [sum. 26]
