The pattern is as follows
(7 – 3)2 = 16; (10 – 4)2 = 36
The missing number is (12 – 3)2 = 92 = 81.
So 81 replaces the '?'
(7 – 3)2 = 16; (10 – 4)2 = 36
The missing number is (12 – 3)2 = 92 = 81.
So 81 replaces the '?'

Om Desai answered |
The pattern is as follows:
(32 + 42 + 52) = 50
(52 + 62 + 72) = 110
So, Missing value = (42 + 42 + 52) = 16 + 16 + 25 = 57
(32 + 42 + 52) = 50
(52 + 62 + 72) = 110
So, Missing value = (42 + 42 + 52) = 16 + 16 + 25 = 57

Missing number = (9 × 4 × 8) ÷ 4 = 9 × 8 = 72
(10 × 5 × 12) ÷ 4 = 150
Missing number = (9 × 4 × 8) ÷ 4 = 9 × 8 = 72

Om Desai answered |
(10 + 20 + 30) × 2 = 120; (15 + 25 + 35) × 2 = 150.
So, missing number = (10 + 15 + 25) × 2 = 100.
So, missing number = (10 + 15 + 25) × 2 = 100.

Half of the sum of the number outside the circle gives the number inside the circle.
Missing number = (4 + 3 + 1 + 3) ÷ 2 = 11 ÷ 2 = 5.5
Missing number = (4 + 3 + 1 + 3) ÷ 2 = 11 ÷ 2 = 5.5

(Top number × Bottom number) ÷ (Left number × Right number) gives the middle number.
Missing number = (22 × 6) ÷ (3 × 11) = 132 ÷ 33 = 4

(8 + 7 + 5 + 4) = 24 ⇒ 2 + 4 = 6
(9 + 8 + 8 + 6) = 31 ⇒ 3 + 1 = 4
The missing number is (12 + 13 + 6 + 5) = 36 ⇒ (3 + 6) = 9.
(9 + 8 + 8 + 6) = 31 ⇒ 3 + 1 = 4
The missing number is (12 + 13 + 6 + 5) = 36 ⇒ (3 + 6) = 9.
