In each of the given number-clusters, the number on the
right side of = (the equal to sign) is calculated by performing certain mathematical operations on the four numbers on the left of (the equal to sign).

Select the number from among the given options that can replace the question mark (?) in the third number-cluster 11, 8, 5, 9 = 43 12, 9, 7, 6 = 66 14, 13, 9, 10 =?Solution
The logic is- 11 x 8 – 5 x 9 = 88 – 45 = 43 12 x 9 – 7 x 6 = 108 – 42 = 66 14 x 13 – 9 x 10 = 182 – 90 = 92
