Here are 1000+ Logical Reasoning Questions and Answers (Topic wise).
1. Find the odd one out from the given set of numbers.
14, 28, 35, 46, 56, 84
a) 56
b) 84
c) 35
d) 46
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.
2. Find odd one out from the given jumbled words.
LNUAIMMIU, ELEST, OPERPC, NMKOYE, INCKLE
a) NMKOYE
b) OPERPC
c) INCKLE
d) ELEST
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.
3. Find the odd one out.
a) BEK
b) CFL
c) MPS
d) GJP
View Answer
Explanation: Here, the letters given follows the below pattern
C + 3 ➔ F + 6 ➔ L
B + 3 ➔ E + 6 ➔ K
G + 3 ➔ J + 6 ➔ P
But MPS does not follow this pattern (i.e. M + 3 ➔ P + 3 ➔ S).
Hence, MPS is the answer.
4. Find the odd one out.
a) M
b) S
c) T
d) O
View Answer
Explanation: Here, the letters M, O and T have exactly same mirror images.
i.e.
M | M O | O T | T
But, letter S has inverted mirror image (i.e. S | Ꙅ).
Hence, S is the answer.
5. In a certain code “CODE” is written as “DPEF”. How is “DEFENCE” is written in that code?

i.e.
1247 - 180 = 1067 2361 - 180 = 2181 3429 - 180 = 3249
But, 7258 – 180 ≠ 7124.
