Latest Classification MCQ Objective Questions

Classification Question 1:

Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which letter-cluster pair DOES NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter cluster)

  1. MU - KH
  2. HL - JN
  3. SW - UY
  4. NR - PT

Answer (Detailed Solution Below)

Option 1 : MU - KH

Classification Question 1 Detailed Solution

Given:

Option 1) MU - KH

M(13) U(21)
↓ -2 ↓ -13
K(11) H(8)

Option 2) HL - JN

H(8) L(12)
↓ +2 ↓ +2
J(10) N(14)

Option 3) SW - UY

S(19) W(23)
↓ +2 ↓ +2
U(21) Y(25)

Option 4) NR - PT

N(14) R(18)
↓ +2 ↓ +2
P(16) T(20)

Options 2, 3, and 4 follow the same pattern where each letter shifts forward by 2 positions. Option 1 follows a different pattern of making it the odd one out.

Hence, the correct answer is "Option 1".

Classification Question 2:

Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster DOES NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

  1. ECG
  2. SQU
  3. LJN
  4. POR

Answer (Detailed Solution Below)

Option 4 : POR

Classification Question 2 Detailed Solution

The logic followed in this pattern is based on alphabetical shifts between consecutive letters within each cluster.

For 'ECG':                    

E C G  
  -2   +4    

For 'SQU':                     

S Q U  
  -2   +4    

For 'LJN':            

L J N  
  -2   +4    

For 'POR':              

P O R  
  -1   +3    

 

Thus, the letter-cluster that DOES NOT belong to that group is " POR".

Hence, the correct answer is "Option 4".

Classification Question 3:

Select the odd word from the given alternatives:

  1. FHK
  2. QSV
  3. MOR
  4. TUW
  5. LNQ

Answer (Detailed Solution Below)

Option 4 : TUW

Classification Question 3 Detailed Solution

FHK → F + 2 = H, H + 3 = K.

QSV → Q + 2 = S, S + 3 = V.

MOR → M + 2 = O, O + 3 = R.

TUW → T + 1 = U, U + 2 = W.

LNP → L + 2 = N, N + 3 = Q.

Hence, ‘TUW’ is the odd one out. 

Classification Question 4:

Find the ODD one out from the given options.

  1. 280
  2. 325
  3. 226
  4. 145
  5. None of the above

Answer (Detailed Solution Below)

Option 1 : 280

Classification Question 4 Detailed Solution

The logic followed here is:

280 is not a square number + 1,

Whereas,

325 = 182 + 1, 226 = 152 + 1, 145 = 122 + 1.

So, 280 is odd from the given options.

Hence, the correct answer is "Option 1".

Classification Question 5:

Out of the given options, three are similar in a certain manner However one option is not like the other three. Select the one that is different from he rest. 

  1. 216
  2. 729
  3. 1331
  4. 324
  5. None of the above

Answer (Detailed Solution Below)

Option 4 : 324

Classification Question 5 Detailed Solution

The logic is:

1. 216 → 63

2. 729 → 93 

3. 1331 → 113

4. 324 → 182

Clearly, all options except '324' are perfect cubes, while '324' is a perfect square.

Hence, ‘324’ is the odd one out.
