Ans:- 15

If You add both sides' number of diameters, You will found that they are equal to 37. I.e.
13 + 24 =37
21 + 16 =37
25 + 12 =37
So the missing number is 37 - 22 = 15

This is out-of-the-box thinking. My way to calculate the answer to this logic puzzle was different. However, my answer will also lead to this conclusion.
My answer was to sum of half Circle numbers and the sum of all the digits inside the Circle is 37 and it will get divided into two parts.
Thanks for looking at this problem differently. Looking forward to your comments on similar puzzles.
