In this type of question in reasoning section, the candidate has to choose one of the alternatives. Out of the given alternatives, only one is different from the rest. This different term is your answer. This type of questions are better understood through examples, therefore, lets begin:

Example 1;
Which of the given words is different from the rest?

  1. Dog
  2. Lion
  3. Cat
  4. Ox

Example 2;
Which among the following numbers is different from the rest?

  1. 13
  2. 17
  3. 21
  4. 19

Answer : Look closely at all the given numbers, 13 is a prime number. So is 17 and also 19. Only 21 is the one which is not a prime number but a composie number. Hence the answer to this question is 21.

Example 3;
Which one among the following groups of letters is different from the rest?

  1. NP
  2. US
  3. PR
  4. EG

Answer : As is evident upon analyzing the alphabets, Only in ‘US’ the series is moving in -2 direction as compared to other three where +2 pattern is being followed. Hence, the answer is US.

Example 4;
Which one word among the following options does not belong to the group?

  1. Wheat
  2. Paddy
  3. Maize
  4. Mustard

Answer : This should be simple if you have a little knowledge about these four. Only Mustard is the one which is not a cereal. Hence answer is Mustard.

  1. Mother-father
  2. Grandfather-Grandson
  3. Mother-in-law — Father-in-law

Example 7;
From the given group of numbers, find the odd one?

  • 41
  • 47

  1. Foggy
