This set of Logical Reasoning Questions and Answers (MCQs) focuses on “Odd Man Out – Set 4”.
1. Find the odd one out.
a) Figure A
b) Figure B
c) Figure C
d) Figure D
View Answer
Explanation: Here, the symbols in the box follows a pattern in their positions (That is their position + 2) rotating clockwise. But in figure D the symbol ‘Ω’ and ‘α’ are not in the correct positions.
(That is Ω is in + 1 position while α is in + 3 position).
Hence, figure D is the answer.
2. Find the odd one out.
a) Ngultrum
b) Pula
c) Chilean peso
d) Aventurine
View Answer
Explanation: Here, Ngultrum is the currency of Bhutan, Pula is the currency of Botswana and Chilean peso is the currency of Chile. But Aventurine is a form of quarts which neutralizes all sources of electromagnetic pollution and is believed to bring well – being and emotional calm.
Hence, Aventurine is the answer.
3. Find the odd one out from the following figures.
a) A
b) B
c) C
d) D
View Answer
Explanation: In all the figures the sum of the number of edges of the figure inside the box is odd.
i.e.
C ➔ 6 + 3 = 9 (odd) D ➔ 5 + 6 = 11 (odd) B ➔ 5 + 4 = 9 (odd)
But in figure A:-
A ➔ 4 + 4 = 8 (even)
Hence, figure A is the answer.
4. Find the odd one out.
a) E
b) Y
c) W
d) T
View Answer
Explanation: Here, it requires even numbers of lines to write the letters. ‘E’, ‘W’ and ‘T’
i.e.
E ➔ 4 Lines {| - - - }
W ➔ 4 Lines {\ / \ /}
T ➔ 2 Lines {| -}
But only 3 lines are used to write ‘Y’ (i.e. \ / |) which is odd.
Hence, Y is the answer.
5. Find the odd one out.
a) 43 : 1728
b) 23 : 216
c) 31 : 27
d) 45 : 67
View Answer
Explanation: Here, the options follows a pattern: –
43 : 1728 ⇒ 4 × 3 = 12 : 123 = 1728; 23 : 216 ⇒ 2 × 3 = 6 : 63 = 216; 31 : 27 ⇒ 3 × 1 = 3 : 33 = 27;
But 45 : 67 does not follow this patters (4 × 5 = 20 : 203 ≠ 67).
Hence, 45 : 67 is the answer.
6. Find the odd one out.
a) BGJ
b) EJM
c) KPS
d) RTY
View Answer
Explanation: Here, the letters given follows a pattern: –
B + 5 ➔ G + 3 ➔ J E + 5 ➔ J + 3 ➔ M K + 5 ➔ P + 3 ➔ S
But RTY does not follow this pattern (that is, R + 2 ➔ T + 5 ➔ Y).
Hence, RTY is the answer.
7. Find the odd one out.
a) 2:4:12
b) 5:10:30
c) 7:14:42
d) 9:18:72
View Answer
Explanation: Here, the numbers given in the data follows a pattern
i.e.
2 × 1 ➔ 2 × 2 ➔ 4 × 3 = 12 5 × 1 ➔ 5 × 2 ➔ 10 × 3 = 30 7 × 1 ➔ 7 × 2 ➔ 14 × 3 = 42
But 9 × 1 ➔ 9 × 2 ➔ 18 × 3 ≠ 72
Hence, 9:18:72 is the answer.
8. Find the odd one out.
a) Carbon
b) Boron
c) Oxygen
d) Iron
View Answer
Explanation: Here, the given options Carbon, Boron and Oxygen are p – block elements (their valance shell electronic configuration is ns2np1-6).
Whereas, Iron is a d – block element (their valance shell electronic configuration is (n – 1)d1-10ns1-2).
Hence, Iron is the answer.
9. Find the odd one out.
a) Fahrenheit
b) Celsius
c) Kelvin
d) Joules
View Answer
Explanation: Here, Fahrenheit(°F), Celsius(°C) and Kelvin(K) are all units to measure temperature.
Whereas, Joules(J) is the unit of Energy.
Hence, Joules is the answer.
10. Find the odd one out from the given data.
24, 54, 63, 72, 90
a) 24
b) 54
c) 63
d) 72
View Answer
Explanation: Here, the numbers 24, 54, 72 and 90 are divisible by 6 (multiple of 6).
i.e.
24 ÷ 6 = 4 54 ÷ 6 = 9 72 ÷ 6 = 12 90 ÷ 6 = 15
But 63 in the given data is not divisible by 6 (i.e. not a multiple of 6).
Hence, 63 is the answer.
