Question

In the following question, some groups of letters are given, all of which except one, share a common similarity while one is different. Select the odd one.

• A. $\text{DFHB}$
• B. $\mathrm{KMOJ}$
• C. $\text{PRTN}$
• D. $\text{XZBV}$

   

Answer 1

We are given with 4 options and we have to check which option doesn’t match with the pattern of other three.

Here the recognized pattern is as follows : 

Last Letter  → Skip one letter in alphabetical order → First Letter → Skip one letter in alphabetical order →  

Second Letter → Skip one letter in alphabetical order →  Third Letter.

 

Here, Skip one letter in alphabetical order means : If A is written → skip B → write C.  

 

Now, Let’s check the options : -

Option A : D F H B : B → Skip C → D → Skip E → F → Skip G → H. Option A is valid.

Option B : K M O J : J → Skip K → L. Option B doesn’t follow this pattern. Let’s check for C & D.

Option C : P R T N : N → Skip O → P → Skip Q → R → Skip S → T. Option C also valid.

Option D : X Z B V : V → Skip W → X → Skip Y → Z → Skip A → B. Option D is also valid.

 

We have to find out the option which is different from other 3 options.

So, Option B is correct answer.

Answer 2

• $D\xrightarrow{+2}F\xrightarrow{+2}H\xrightarrow{-6}B$
• $K\xrightarrow{+2}M\xrightarrow{+2}O\xrightarrow{-5}J$
• $P\xrightarrow{+2}R\xrightarrow{+2}T\xrightarrow{-6}N$
• $X\xrightarrow{+2}Z\xrightarrow{+2}B\xrightarrow{-6}V$

Option $(B)$ is correct.
