Number Based Question 1:

Below are given two sets of numbers. In each set of numbers, a certain mathematical operation on the first number results in the second number. Similarly, a certain mathematical operation on the second number results in the third number and so on. Which of the given options follows the same set of operations as in the question? (NOTE – A two/three-digit number cannot be broken into individual digits for operations, e.g. if 37 is followed by 10, the operation cannot be 3+7 as a two-digit number cannot be broken into individual digits.)
11 - 12 - 13 - 26 ; 19 - 20 - 21 - 42

  1. 4 - 5 - 6 - 10
  2. 7 - 8 - 9 - 18
  3. 3 - 4 - 5 - 12
  4. 9 - 10 - 11 - 24

Answer (Detailed Solution Below)

Option 2 : 7 - 8 - 9 - 18

Number Based Question 1 Detailed Solution

The logic followed here is:

Given: 

11 - 12 - 13 - 26

11 + 1 = 12

12 + 1 = 13

13 × 2 = 26

And,

19 - 20 - 21 - 42

19 + 1 = 20

20 + 1 = 21

21 × 2 = 42

So, checking each option one by one:

Option 1) 4 - 5 - 6 - 10

4 + 1 = 5

5 + 1 = 6

6 × 2 = 12 ≠ 10

Option 2) 7 - 8 - 9 - 18

7 + 1 = 8

8 + 1 = 9

9 × 2 = 18

Option 3) 3 - 4 - 5 - 12

3 + 1 = 4

4 + 1 = 5

5 × 2 = 10 ≠ 12

Option 4) 9 - 10 - 11 - 24

9 + 1 = 10

10 + 1 = 11

11 × 2 = 22 ≠ 24

Thus, out of all the options '7 - 8 - 9 - 18' follows the same logic as given.

Hence, "Option 2" is the correct answer.

Number Based Question 2:

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

Number Based Question 2 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".

Number Based Question 3:

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

Number Based Question 3 Detailed Solution

Positional value Table

The logic followed here is,

Option 1) # = JRM, % = COP

qImage686ba330d75c0608fc80909f

Option 2)  # = JPT, % = CKR

qImage686ba330d75c0608fc8090a0

Option 3) # = JPR, % = CKO

qImage686ba331d75c0608fc8090a3

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

Option 4)  # = JQM, % = CPK

qImage686ba331d75c0608fc8090a4

Hence, the correct answer is "Option 3".

Number Based Question 4:

Below are given two sets of numbers. In each set of numbers, a certain mathematical operation on the first number results in the second number. Similarly, a certain mathematical operation on the second number results in the third number and so on. Which of the given options follows the same set of operations as in the question? (NOTE – A two/three-digit number cannot be broken into individual digits for operations, e.g. if 37 is followed by 10, the operation cannot be 3+7 as a two-digit number cannot be broken into individual digits.)
3 - 5 - 10 - 12 ; 8 - 10 - 20 - 22

  1. 4 - 6 - 12 - 24
  2. 28 - 30 - 60 - 64
  3. 6 - 10 - 12 - 24
  4. 18 - 20 - 40 - 42

Answer (Detailed Solution Below)

Option 4 : 18 - 20 - 40 - 42

Number Based Question 4 Detailed Solution

The logic followed here is:

Logic: 1st number + 2 = 2nd number × 2 = 3rd number + 2 - 4th number.

For, 3 - 5 - 10 - 12

⇒ 3 + 2 = 5 × 2 = 10 + 2 = 12.

For, 8 - 10 - 20 - 22

⇒ 8 + 2 = 10 × 2 = 20 + 2 = 22.

Option 1) 4 - 6 - 12 - 24

⇒ 4 + 2 = 6 × 2 = 12 + 2 = 14 ≠ 24. 

Option 2) 28 - 30 - 60 - 64

⇒ 28 + 2 = 30 × 2 = 60 + 2 = 62 ≠ 64. 

Option 3) 6 - 10 - 12 - 24

⇒ 6 + 2 = 8 × 2 = 16 + 2 = 18 ≠ 24. 

Option 4) 18 - 20 - 40 - 42

⇒ 18 + 2 = 20 × 2 = 40 + 2 = 42.

Hence, the correct answer is "Option 4".

Number Based Question 5:

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 ::?
# : AND :: RWX : %

  1. # = XQB, % = UTZ
  2.  # = LCT, % = XQB
  3.  # = OZV, % = LCT
  4. # = UTZ, % = OZV

Answer (Detailed Solution Below)

Option 1 : # = XQB, % = UTZ

Number Based Question 5 Detailed Solution

qImage686cfb55282d524b318c8bad

The logic followed here is:

Given: # : AND :: RWX : %

Option 1) # = XQB, % = UTZ

qImage686cfb56282d524b318c8bbb

Here, it does follow the pattern.

Option 2)  # = LCT, % = XQB

qImage686cfb57282d524b318c8bbc

Option 3)  # = OZV, % = LCT

qImage686cfb57282d524b318c8bbe

Option 4) # = UTZ, % = OZV

qImage686cfb57282d524b318c8bbf

Hence, the correct answer is "Option 1".

Given:

(121, 81, 2)

(88, 54, 2)

Logic: Third no. = [(First no. ÷ 11) - (Second no. ÷ 9)]

(121, 81, 2) 

⇒ [(121 ÷ 11) - (81 ÷ 9)]

⇒ (11 - 9) = 2

(88, 54, 2) 

⇒ [(88 ÷ 11) - (54 ÷ 9)]

⇒ (8 - 6) = 2

Checking all the given options:

1. (13, 5, 9)

⇒ [(13 ÷ 11) - (5 ÷ 9)]

⇒ (1.18 - 0.55) = 0.625

2. (78, 6, 45)

⇒ [(78 ÷ 11) - (6 ÷ 9)]

⇒ (7.09 - 0.66) = 6.394

3. (31, 56, 98)

⇒ [(31 ÷ 11) - (56 ÷ 9)]

⇒ (2.81 - 6.22) = (-3.41)

4. (77, 18, 5)

⇒ [(77 ÷ 11) - (18 ÷ 9)]

⇒ (7 - 2) = 5

Here, (77, 18, 5) shows a similar relation to the given set of numbers.

Hence, the correct answer is "Option (4)".

Answer (Detailed Solution Below)

Option 1 : 25

Number Based Question 7 Detailed Solution

Download Solution PDF

Logic : (1st number × 2nd number × 3) - 2 = (3rd number )

So,

  • (6, 2, 34)

6 × 2 × 3 - 2 = 34 

36 - 2 = 34 (LHS = RHS)

And,

  • (1, 5, 13)

1 × 5 × 3 - 2  = 13

13 = 13 (LHS = RHS)

Similarly,

  • (9, 1, ?)

9 × 1 × 3 - 2 = ? 

27 - 2 = ?

25 = ?

Hence, "25" is the correct answer.

Select the set in which the numbers are related in the same way as are the numbers of the following sets.

The logic followed here is:

Logic: (1st number ÷ 5) + (2nd number ÷ 3) = 3rd number.

Now,

For, (15, 21, 10)

→ (15 ÷ 5) + (21 ÷ 3)

→ 3 + 7 = 10.

For, (25, 36,17)

→ (25 ÷ 5) + (36 ÷ 3)

→ 5 + 12 = 17.

Similarly, for (100, 33, 31)

→ (100 ÷ 5) + (33 ÷ 3)

→ 20 + 11 = 31.

Hence, the correct answer is "Option 2".

The logic followed here is:

Logic: (First number + Second number) × (2/3) = Third number

  • (82, 35, 78) → (82 + 35) × (2/3) = 117 × (2/3) = 78
  • (18, 27, 30) → (18 + 27) × (2/3) = 45 × (2/3) = 30

Similarly,

  • (27, 33, 40) → (27 + 33) × (2/3) = 60 × (2/3) = 40

Hence, '(27, 33, 40)' is the correct answer.

The pattern follows here is:

(First number + 7 ) × 7 : Second number

→  21: 196 

= ( 21 + 7) × 7 

= 28 × 7 

= 196

→ 38: 315

= (38 + 7) × 7

= 45 × 7

= 315

Similarly,

→ 29:?

= (29 + 7 ) × 7

= 36  × 7

= 252

Hence the correct answer is 252. 

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

The logic followed here is:

Logic: (First number × 3 + 1) + Second number = Third number

  • First row - 8, 28, 53 → (8 × 3 + 1) + 28 = (24 + 1) + 28 = 25 + 28 = 53
  • Second row - 7, 25, 47 → (7 × 3 + 1) + 25 = (21 + 1) + 25 = 22 + 25 = 47

Similarly,

  • Third row - 13, 43, ? → (13 × 3 + 1) + 43 = (39 + 1) + 43 = 40 + 43 = 83

Hence, '83' is the correct answer.

The logic followed here is:

Logic: (First number)2 - (Second number ÷ 2)3 = Third number

  • (12, 8, 80) → 122 - (8 ÷ 2)3 = 144 - 43 = 144 - 64 = 80
  • (16, 10, 131) → 162 - (10 ÷ 2)3 = 256 - 53 = 256 - 125 = 131

Similarly,

  • (9, 6, 54) → 92 - (6 ÷ 2)3 = 81 - 33 = 81 - 27 = 54

Hence, '(9, 6, 54)' is the correct answer.

The logic followed here is: First Number2 × (First number - 3) = Second number.

1) (8, 320) ⇒ 82 × (8 - 3) = 64 × 5 = 320

2) (11, 968) ⇒112 × (11 - 3) = 121 × 8 = 968

3) (5, 100) ⇒ 52 × (5 - 3) = 25 × 2 = 50 ≠ 100

4)  (6, 108) ⇒ 62 × (6 - 3) = 36 × 3 = 108

Hence, the correct answer is "(5, 100)".

11 × 2 = 20

22 ≠ 20 (LHS ≠ RHS)

  • Option - (3) : (44, 20, 54)

(44 - 20) × 2 = 54 - 5

24 × 2 = 49

48 ≠ 49 (LHS ≠ RHS)

  • Option - (4) : (35, 22, 34)

(35 - 22) × 2 = 34 - 5

13 × 2 = 29

26 ≠ 29 (LHS ≠ RHS)
