Question
In the following number - pairs, the second number is
obtained by applying certain mathematical operations to the first number. In three of the four pairs, the same pattern is applied and hence they form a group. Select the number - pair that DOES NOT belong to this group.Solution
The logic followed here is as follows: In all of the above pair, the absolute difference between 1st and 2nd number is '216'. Among the given options, in the pair given in option '2' the absolute difference between 1st and 2nd number is (359 - 153) = 206.
