Answer 2

Answer:

The answer is 21.

Step-by-step explanation:

if you add all the numbers in the 1st column and subtract the sum of the numbers in second column, you get 12.

12 is the difference between the sum of each column .

therefore, the sum of third column must be 48.

which implies that 11+5+11+?=48.

hence, the answer is 21
