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
Answer (Detailed Solution Below)
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.)
Answer (Detailed Solution Below)
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 : %
Answer (Detailed Solution Below)
Number Based Question 3 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
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
Answer (Detailed Solution Below)
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 : %
Answer (Detailed Solution Below)
Number Based Question 5 Detailed Solution
The logic followed here is:
Given: # : AND :: RWX : %
Option 1) # = XQB, % = UTZ
Here, it does follow the pattern.
Option 2) # = LCT, % = XQB
Option 3) # = OZV, % = LCT
Option 4) # = UTZ, % = OZV
Hence, the correct answer is "Option 1".

Answer (Detailed Solution Below)
Number Based Question 7 Detailed Solution
Download Solution PDFLogic : (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.

Answer (Detailed Solution Below)
Number Based Question 8 Detailed Solution
Download Solution PDFThe 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".

(18, 27, 30)
Answer (Detailed Solution Below)
Number Based Question 9 Detailed Solution
Download Solution PDFThe 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.

Answer (Detailed Solution Below)
Number Based Question 10 Detailed Solution
Download Solution PDFThe 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.

Number Based Question 11 Detailed Solution
Download Solution PDFThe 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.

Number Based Question 12 Detailed Solution
Download Solution PDFThe 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.
