This set of Logical Reasoning Questions and Answers (MCQs) focuses on “Odd Man Out”. These questions are beneficial for various competitive exams, placement interviews, and entrance tests.
1. Find the odd one out from the given set of numbers.
2, 4, 8, 11, 14, 18
a) 2
b) 8
c) 11
d) 14
View Answer
Explanation: Here, the numbers 2, 4, 8, 14 and 18 from the given data are divisible by 2 (i.e. even numbers).
Whereas number 11 from the given data is not divisible by 2 (i.e. an odd number).
Hence 11 is the answer.
2. Find the odd one out from the given set of numbers.
16, 81, 100, 256, 2401
a) 2401
b) 100
c) 81
d) 16
View Answer
Explanation: The numbers in the given data are the fourth power of a number.
i.e.
24 = 16 34 = 81 44 = 256 74 = 2401
But the number 100 in the given data is not a fourth power of any number.
Hence 100 is the answer.
3. Find the odd one out from the given set of numbers.
14, 28, 35, 46, 56, 84
a) 35
b) 46
c) 56
d) 84
View Answer
Explanation: Here, the numbers 14, 28, 35, 56 and 84 are perfectly divisible by 7.
i.e.
14 ÷ 7 = 2 28 ÷ 7 = 4 35 ÷ 7 = 5 56 ÷ 7 = 8 84 ÷ 7 = 12
But the number 46 is not perfectly divisible by 7 (i.e. not a multiple of 7).
Hence, 46 is the answer.
4. Find the odd one out from the given set of numbers.
121, 385, 462, 561, 678, 792
a) 121
b) 462
c) 678
d) 792
View Answer
Explanation: Here, the middle digit of the number is the sum of other two digits of that number.
i.e.
1 + 1 = 2 ⇒ 121 3 + 5 = 8 ⇒ 385 4 + 2 = 6 ⇒ 462 5 + 1 = 6 ⇒ 561 7 + 2 = 9 ⇒ 792
But the number 678 in the given data does not follow this pattern (i.e. middle digit is not the sum of other two digits).
Hence, 678 is the answer.
5. Find the odd one out from the given set of numbers.
5, 7, 11, 17, 19, 21
a) 7
b) 11
c) 17
d) 21
View Answer
Explanation: Here, the numbers 5, 7, 11, 17 and 19 in the given data are divisible only by ‘1’ or by the number itself (i.e. are prime numbers). Whereas the number 21 in the given data is also divisible by ‘3’ (21 ÷ 3 = 7) other than ‘1’ and ‘21’ (i.e. not a prime number).
Hence, 21 is the answer.
6. Find the odd one out from the given data.
EFG, BCE, JKL, ABC, NPO
a) NPO
b) JKL
c) BCE
d) ABC
View Answer
Explanation: Here, the group of letters EFG, BCE, ABC and NPO contain vowels in it (i.e. a, e, i, o and u).
i.e. EFG, BCE, ABC and NPO
Whereas JKL in the given data, does not contain any vowel in it.
Hence, JKL is the answer.
7. Find the odd one out from the given data.
RED, BLACK, GREY, ORANGE, VIOLET
a) BLACK
b) RED
c) ORANGE
d) VIOLET
View Answer
Explanation: There are 3 primary colors which are RED, YELLOW and BLUE.
In the given data, RED is the only primary color given. Whereas BLACK, ORANGE, GREY and VIOLET in the given data are not considered as primary colors.
Hence, RED is the answer.
8. Find odd one out from the given jumbled words.
LNUAIMMIU, ELEST, OPERPC, NMKOYE, INCKLE
a) INCKLE
b) ELEST
c) NMKOYE
d) OPERPC
View Answer
Explanation: The Rearrangement of the words are : –
LNUAIMMIU ⇒ ALUMINIUM
ELEST ⇒ STEEL
OPERPC ⇒ COPPER
NMKOYE ⇒ MONKEY
INCKLE ⇒ NICKLE
Here the odd one out is MONKEY, as all others are names of the elements that exist in the nature.
9. Find the odd one out from the given data.
ZCA, WFD, UHF, SJH, PKG
a) WFD
b) UHF
c) PKG
d) ZCA
View Answer
Explanation: Let n = 1(i.e. A) and m = 26(i.e. Z) in the alphabets.
Here these groups of letters follow the pattern of (m – a) (n + a + 2) (n + a).
For
ZCA = (m - 0) (n + 0 + 2) (n + 0) WFD = (m - 3) (n + 3 + 2) (n + 3) UHF = (m - 5) (n + 5 + 2) (n + 5) SHJ = (m - 7) (n + 7 + 2) (n + 7)
But PKG does not follow this pattern. Hence, PKG is the answer.
10. Find the odd one out from the given data.
DFH, PLN, RTX, BNV, MFK
a) DFH
b) MFK
c) RTX
d) BNV
View Answer
Explanation: Here, these group of letters have a position of even number in the English alphabet.
Like
D = 4, F = 6, H = 8 P = 16, L = 12, N = 14 R = 18, T = 20, X = 24 B = 2, N = 14, V = 22
But M = 13, so MFK is the answer.
