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). All three number-clusters follow the same pattern. 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
