Ans: 2.

Explanation:

     

     You can find many 2x2 tables in the figure. Each 2x2 table contains 4 digits which should get the sum of 15.

        Lets image first 2x2 table which contain values 5, 7 in the first row and 1,2 in the second row. 

        5 + 7 + 1 + 2 = 15 

Second 2x2 tables contains 7, 4, 2, 2

        7 + 4 + 2 + 2 = 15

If you follow this pattern, you will get more 2x2 tabels, and sum of each digits in the 2x2 tables should be 15 as below.

        4 + 3 + 2 + 6 = 15 

        3 + 1 + 6 + 5 = 15 

        1 + 2 + 6 + 6 = 15

        2 + 2 + 6 + 5 = 15 

        2 + 6 + 5 + 2 = 15 

        6 + 6 + 1 + 2 = 15
