Question

Can you find the value of the missing number in the fourth circle?

Answer 1

To get the number in the white sector of each circle:
1. We have to first add all the 3 digits in the green sectors of the circle
2. Then divide the sum by 2.
For Instance:

1] 32 + 24 + 48 = 104
104/2 = 52

2] 23 + 35 + 46 = 104
104/2 = 52

3] 16 + 38 + 54 = 108
108/2 = 54

4] 27 + 33 + 42 = 102
102/2 = 51.

Answer 2

Green numbers summed up / 2 = White number
27 + 33 + 42 = 102 / 2 = 51
Missing number = 51
