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.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituentdigits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
- A.
335 - 119
- B.
358 - 152
- C.
317 - 101
- D.
308 - 92
Attempted by 24 students.
Show answer & explanation
Correct answer: B
The pattern involves subtracting 216 from the first number to get the second. Pairs (335, 119), (317, 101), and (308, 92) follow this rule. Pair (358, 152) does not fit as 358 - 216 = 142, not 152. Thus, Option B is the outlier.
