Question
Four number-pairs are given, three of which are alike in
certain manner and one is different. Choose the different number-pair.Solution
The pattern followed here is: The product of the digits of the 1st number is subtracted from the 1st number to get the 2nd number. In option 'A', 1st number = 674, 2 nd number = 674 - (6 X 7 X 4) = 506 In option 'B', 1st number = 496, 2 nd number = 496 - (4 X 9 X 6) = 280 In option 'C', 1st number = 583, 2 nd number = 583 - (5 X 8 X 3) = 463 ≠433 In option 'D', 1st number = 787, 2 nd number = 787 - (7 X 8 X 7) = 395
