The numbers in the circle appear random at first, but if you think hard and perform the basic arithmetic operations: addition, subtraction, multiplication and subtraction, you’ll notice a pattern.
Here are the steps to reach the solution.
- Observe the first circle and pair the opposites 5 & 9, and 8 & 6.
- Multiply both pairs
You get (5 x 9) = 45 & (8 x 6) = 48
- Now calculate the difference and find its square
48 - 45 = 3
- Now squaring it,
32 = 9
Similarly for the second circle:
(11 x 2) = 22 & (5 x 3) = 15
=> 22 - 15 = 7
=> 72 = 49
And finally coming to Circle Three:
(12 x 9) = 108 & (7 x 14) = 98
=> 60 - 54 = 10
=> 102 = 100
And there’s your answer.
