In the following question, four groups of three numbers are given. In each group the second and third number are related to the first number by a Logic/Rule/Relation. Three are similar on the basis of the same Logic/Rule/Relation. Select the odd one out from the given alternatives.
- A(83,97,113)
- B(47,61,75)
- C(34,48,62)
- D(64,78,92)
Solution & Step-by-step Explanation
Let's check the differences within each group:
Option B: 61−47=14; 75−61=14 (Differences are +14,+14)
Option C: 48−34=14; 62−48=14 (Differences are +14,+14)
Option D: 78−64=14; 92−78=14 (Differences are +14,+14)
Let's check Option A:
97−83=14
113−97=16
Since option A has differences of +14 and +16, it does not follow the +14,+14 constant difference rule followed by the other options.
Option B: 61−47=14; 75−61=14 (Differences are +14,+14)
Option C: 48−34=14; 62−48=14 (Differences are +14,+14)
Option D: 78−64=14; 92−78=14 (Differences are +14,+14)
Let's check Option A:
97−83=14
113−97=16
Since option A has differences of +14 and +16, it does not follow the +14,+14 constant difference rule followed by the other options.
