Question
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 two 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 69, 87 = 39 93, 95 = 47 52, 64 = ?Solution
The logic is- 69 + 87 = 156/4 = 39 93 + 95 = 188/4 = 47 52 + 64 = 116/4 = 29
