Latest Logical Reasoning MCQ Objective Questions

Logical Reasoning Question 1:

GV 14 is related to LS 5 in a certain way. In the same way, HQ 5 is related to MN -4. To which of the given options is MG 0 related, following the same logic?

  1. BG -7
  2. HR -3
  3.  NY -6
  4.  RD -9

Answer (Detailed Solution Below)

Option 4 :  RD -9

Logical Reasoning Question 1 Detailed Solution

The pattern involves two distinct logics applied to the letters and the numbers separately.

Logic for Letters: The first letter shifts by +6 positions and the second letter shifts by -3 positions in the alphabetical order.

Logic for Numbers: The numbers change by -9.

For 'GV 14' related to 'LS 5':

For 'HQ 5' related to 'MN -4':

Applying the same logic to 'MG 0':

Thus, MG 0 is related to SD -9.

Hence, the correct answer is "Option 4".

Logical Reasoning Question 2:

Direction: Study the following information carefully to answer the given questions:

7 % A M G K @ 1 # E Y T D 2 ! O 4 L P R * 6 C N Q V

If all the symbols and vowels are dropped out from the above arrangement, then which element will be seventh to the left of the element which is fifth from the right end ?

  1. D
  2. Y
  3. T
  4. R
  5. M

Answer (Detailed Solution Below)

Option 3 : T

Logical Reasoning Question 2 Detailed Solution

Given series:

Left side 7 % A M G K @ 1 # E Y T D 2 ! O 4 L P R * 6 C N Q V Right side

After dropping all the symbols and vowels from the series we get,

Left side 7 M G K 1 Y T D 2 4 L P R 6 C N Q V Right side

Therefore, fifth element from the right end is 6 and T is seventh to the left of 6.

Hence, T is the correct answer. 

Logical Reasoning Question 3:

54 is related to 59 following a certain logic. Following the same logic, 30 is related to 35. To which of the following is 11 related, following the same logic?
 (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

  1. 18
  2. 15
  3. 17
  4. 16

Answer (Detailed Solution Below)

Option 4 : 16

Logical Reasoning Question 3 Detailed Solution

The logic to be followed here is

Logic: Second Number = First Number + 5

For 54 is related to 59

Here, 59 = 54 + 5

30 is related to 35

Here, 35 = 30 + 5

Now, apply the same logic to find the number related to 11:

Let the related number be ?. So, 11 is related to ?.

? = 11 + 5

? = 16

Therefore, 11 is related to 16.

Hence, the correct answer is "Option 4".

Logical Reasoning Question 4:

Which of the following letter-clusters should replace # and % so that the pattern and relationship followed between the letter-cluster pair on the left side of :: is the same as that on the right side of ::?
 # : LQT :: AJM : %

  1. # = JRM, % = COP
  2.  # = JPT, % = CKR
  3. # = JPR, % = CKO
  4.  # = JQM, % = CPK

Answer (Detailed Solution Below)

Option 3 : # = JPR, % = CKO

Logical Reasoning Question 4 Detailed Solution

The logic followed here is,

Option 1) # = JRM, % = COP

Option 2)  # = JPT, % = CKR

Option 3) # = JPR, % = CKO

Here both the letter cetter-clusters follow the same logic.

Option 4)  # = JQM, % = CPK

Hence, the correct answer is "Option 3".

Logical Reasoning Question 5:

Refer to the following number and symbol series and answer the question that follows. Counting to be done from left to right only. All numbers are single-digit numbers.
(Left) 2 * 3 & @ @ 6 4 $ @ 3 * % 6 2 1 3 9 7 8 2 € (Right)
How many such numbers are there each of which is immediately preceded by a number and also immediately followed by a symbol?

  1. 4
  2. 5
  3. 2
  4. 3

Answer (Detailed Solution Below)

Option 3 : 2

Logical Reasoning Question 5 Detailed Solution

Given series:

(Left) 2 * 3 & @ @ 6 4 $ @ 3 * % 6 2 1 3 9 7 8 2 € (Right)

Condition to be checked:

We are looking for a pattern: Number - Number - Symbol

Let's scan the series from left to right:

2 * 3 & @ @ 6 4 $ @ 3 * % 6 2 1 3 9 7 8 2 €

There are 2 such numbers: 4 (in 6 4 $) and 2 (in 8 2 €) which is immediately preceded by a number and also immediately followed by a symbol.

Hence, the correct answer is "Option 3".

How many triangles are there in the given figure?

  1. 13
  2. 32
  3. 21
  4. 24

Answer (Detailed Solution Below)

Option 4 : 24

Logical Reasoning Question 6 Detailed Solution

Hence there are "24" triangles in the figure.

 

First let's count the sections of the given triangle and then add them, then that is the number of triangles.

Lines originating from the top vertex are dividing the triangle into 4 parts. And naming the parts as 1, 2, 3, and 4. (Upper and bottom figure)

Then adding these parts separately we get,

Number of triangles (Upper)= 1 + 2 + 3 + 4 = 10.

Number of triangles (Upper and bottom) = 2 × 10 = 20.

Number of triangles = 4

Thus, total number of triangles = 20 + 4 = 24.

Three of the following four words are alike in a certain way and one is different. Select the odd one.

  1. Goggles
  2. Spectacles
  3. Bifocals
  4. Optical Reader

Answer (Detailed Solution Below)

Option 4 : Optical Reader

As Goggles, spectacles and Bifocals are worn by human beings but Optical reader is not worn , It is a device found within most computer scanners that captures visual information and translates the image into digital information the computer is capable of understanding and displaying. 

Hence, option 4 is the correct answer.

Three of the following four words are alike in a certain way and one is different. Pick the odd one out.

  1. Hendecagon
  2. Hexagon
  3. Heptagon
  4. Pentagon

Answer (Detailed Solution Below)

Option 2 : Hexagon

Logical Reasoning Question 8 Detailed Solution

Here all the polygon are of odd number of sides except hexagone.

Hendecagon is a polygon of 11 sides, Heptagon is a polygon of 7 sides and Pentagon is a polygon of 5 sides.

Only Hexagon is an odd one here as it has even number of sides i.e. 6 sides.

Hence, option 2 is the correct answer.

According to given figure:

The figure will appear when it is opened as follows:

Hence, "Option - (3)" is the correct answer.

Select the option that is related to the fifth number in the same way as the second number is related to the first number and fourth number is related to third number.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 - Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

139 : 228 :: 122 : 211 :: 2 : ?

  1. 91
  2. 198
  3. 89
  4. 189

Answer (Detailed Solution Below)

Option 1 : 91

Logical Reasoning Question 13 Detailed Solution

Download Solution PDF

The pattern followed here is:

Logic: Second number - First number = 89

1) 139 : 228

⇒ 228 - 139 = 89

And,

2) 122 : 211

⇒ 211 - 122 = 89

Similarly,

3) 2 : ?

⇒ X - 2 = 89

⇒ X = 89 + 2

⇒ X = 91

Hence, the correct answer is "91".

Important Points

  •  NOT Related means "We have to find a pair that is different from the given pair."

 

  • The logic followed here is: Second number = First number × (First number ÷ 2)
  • Given: 4 : 8 ⇒ 4 × (4 ÷ 2) = 4 × 2 = 8
  1. 8 : 32 ⇒ 8 × (8 ÷ 2) = 8 × 4 = 32
  2. 2 : 2 ⇒ 2 × (2 ÷ 2) = 2 × 1 = 2
  3. 3 : 9 ⇒ 3 × (3 ÷ 2) = 3 × 1.5 = 4.5 ≠ 9
  4. 6 : 18 ⇒ 6 × (6 ÷ 2) = 6 × 3 = 18

 

Hence, "option 3" is the correct answer.

Study the given pattern carefully and select the number that can replace the question mark (?) in it.

First row - 67, 25, 101

Second row - 55, 17, 97

Third row - 45, 19, ?

(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

  1. 67
  2. 72
  3. 92
  4. 59

Answer (Detailed Solution Below)

Option 4 : 59

Logical Reasoning Question 15 Detailed Solution

Download Solution PDF

The logic followed here is:

(First number × 3) - (Second number × 4) = Third number

First row - 67, 25, 101 → (67 × 3) - (25 × 4) = 201 - 100 = 101

Second row - 55, 17, 97 → (55 × 3) - (17 × 4) = 165 - 68 = 97

Similarly,

Third row - 45, 19, ? → (45 × 3) - (19 × 4) = 135 - 76 = 59

Hence, option 4) is the correct answer.
