Missing Number – Railway Reasoning part – 3

In the 1st fig. -- 12 - 3 + 6 =15,
In the 2nd fig. -- 18 - 6 + 3 = 15
In the 2nd fig. -- 13 - 5 + 12 = 20

Logic:- Power is multiplying with respect to the corresponding circles. By the given figure -
2²×² + 1⁴ײ + 4³×² = 2⁴ + 1 + 4⁶ = 16 + 1 + 4096 = 4113

Logic -
16 × 8 = 128 , 14 ×9 = 126 similarly
16 × 5 = 80

Logic -
In first fig. (4 × 8 ) - ( 6 × 2) = 20
In the 2nd fig. ( 8 × 6) - (5 × 6 ) = 18
In 3rd fig. ( 9 × 2) - (4 × 3 ) = 6

For the first fig. ---- side of triangle × side of square × 3 = 3 × 4 × 3 = 36
For 2nd fig. --- side of square × side of square × 5 = 80
For 3rd fig. --- side of hexagon × side of the triangle × 4 = 72

Logic- (6 + 7) × 9 = 117
Similarly , (9 + 2) × 7 = 77

For 1st fig. 4(side of square) × 5 = 20 , 3 (side of triangle) × 6 = 18
Similarly fig. 3 . -- 6 × 5 = 30 , 3 × 6 = 18

On the bases of given fig.

(4 × 8 ) + (18 × 1) = 50
(6 × 3) + (15 × 5) = 93
(9 × 6) + (7 × 5) = 89
