Tips and Tricks for Odd One Out Questions Questions

Background

• Odd One Out type questions have been recently introduced in the CAT Exam. 
• Out of 34 questions in the Verbal Ability & Reading Comprehension Section, 3 questions are from Odd One Out. 
• These questions come under TITA [Type in the Answer] type of questions wherein one has to type in the number corresponding to the statement that is the odd one. In this article, we will be seeing some amazing Tips & Tricks to Solve the Odd One Out Questions that come in the CAT Exam. 

What exactly are Sentence exclusion or Odd One Out questions?

• Sentence exclusion or Odd One Out questions test one important skill is to detect an anomaly in data. 
• Sentence exclusion is a new twist on the old Para jumbles question. 
• An ‘irregular’ sentence is added to an already haphazard paragraph. 
• Out of the four/ five given sentences, 3/4 sentences are coherent parts of the paragraph and the remaining one is the one that needs to be taken out. 
• This is an extra task for the candidate as he has to not only fish out the odd sentence but also join the sentences so as to form a proper paragraph.

Example: Look at the following words, and find the odd one among them:Taxi  Plane  Bike  Walk

The answer is obvious: Walk

What you did here to solve the question was:

1. First, you read the words in a given order.
2. You figured out that three of them have the common category of ‘vehicles’.
3. You comprehended that the fourth one does not belong to this group and so that is the answer to this question.

This is exactly what has to be done in the Sentence Exclusion or Odd One Out questions in CGL:

1. You have to read the given sentences in that order.
2. Figure out what they have in common, i.e., what is the main common idea linking them together.
3. Confirm the odd sentence that will be incoherent with the paragraph and finalize the correct order (if asked).

How to find what the given sentences have in common?

• The answer is to find the Commonality in the paragraph. The easiest way to figure out the commonality is to find out ‘what is going on in the paragraph’. Find the ‘topic of discussion’, what the author is trying to convey. When you find the ‘topic’, you will figure out which are the sentences that have that ‘subject’ in common.
• The ‘topic’ can commonly be found in the opening sentence of the paragraph. To find the opening sentence, use the usual Para Jumbles technique. The opening sentence mostly chalks out the timeline of the events, the full names of the characters involved, the idea upon which the whole paragraph is built up in the succeeding sentences, and the sentence which does not end abruptly with “however…” or “but…”.
• Once the opening sentence is discovered, the rest of the sentences need to be sorted out in order to find the link and connect them to form a paragraph. The sentence which cannot be connected or linked with the other sentences to be a part of the paragraph is usually the odd one out.

Reverse–way of Identifying the Misfit

The odd sentence is usually made to appear as a part of the paragraph to confuse the candidates. It will usually feature the same people involved or have the same broad theme as discussed in the other sentences (For example, the para may be about WWII, and the misfit may be about WWI). Still, there are some obvious signs to fish out the odd sentence: 

• Inconsistent tense – This is perhaps the most common sign of an odd sentence. The entire paragraph may be in one tense or one-time frame. Then there may be a sentence that sticks out because it has an entirely different tense. 
• Inconsistent tone – The para may be entirely formal or sometimes informal in tone, and the misfit sentence has the opposite tone. 
• The ‘Also’ type – The entire para may talk about one thing that a person or persons has/have been doing. The misfit may talk about something entirely different than the same people may have done. This is usually made difficult due to the commonality of people. 
• The ‘Opposite’ type – The para tries to prove one a thing, the misfit tries to prove the opposite. This may seem easy to spot but is usually made difficult by making the opposition subtle.

To summarize,

1. Find the main theme by finding the opening sentence 
2. Find the one connection, which gives you a reason to single out a misfit 
3. Put the rest of the paragraph together by eliminating the misfit.

CGL Exam Odd One Out | Practice Questions with Solutions:

Now, let’s apply the above-mentioned Tips and Tricks to solve Odd One Out questions in the CAT exam:

Example 1: [Odd One Out for CGL]
