Number Based Question 1:
Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(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.)
(43, 48, 5)
(49, 70, 21)
Answer (Detailed Solution Below)
Number Based Question 1 Detailed Solution
The logic followed here is:
Logic: 3rd number = 2nd number - 1st number.
For, (43, 48, 5)
⇒ 48 - 43 = 5.
For, (49, 70, 21)
⇒ 70 - 49 = 21.
Option 1) (20, 34, 14)
⇒ 34 - 20 = 14.
Here, logic followed.
Option 2) (45, 52, 4)
⇒ 52 - 45 = 7 ≠ 4.
Here, logic not followed.
Option 3) (48, 71, 20)
⇒ 71 - 48 = 23 ≠ 20.
Here, logic not followed.
Option 4) (36, 52, 13)
⇒ 52 - 36 = 16 ≠ 13.
Here, logic not followed.
Hence, the correct answer is "Option 1".
Number Based Question 2:
5 is related to 35 following a certain logic. Following the same logic, 2 is related to 14. To which of the following is 9 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 followed is that the **first number is multiplied by 7** to get the second number.
For 5 : 35,
→ 5 × 7 = 35.
For 2 : 14,
→ 2 × 7 = 14.
Following the same logic for 9 : ?
→ 9 × 7 = 63.
Therefore, 9 is related to 63.
Hence, the correct answer is "Option 1".
Number Based Question 3:
In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the set in which the numbers are related in the same way as are the numbers of the following sets. (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.)
50, 4
80, 7
Answer (Detailed Solution Below)
Number Based Question 3 Detailed Solution
The logic followed here is:
Logic: The second number is obtained by dividing the first number by 10 and then subtracting 1 from the result.
i.e., 2nd number = (1st number ÷ 10) - 1
Let's verify this logic with the given pairs:
For (50, 4):
→ 1st number = 50
→ Check 2nd number: (50 ÷ 10) - 1 = 5 - 1 = 4
→ The given 2nd number is 4. The logic holds for the first pair.
For (80, 7):
→ 1st number = 80
→ Check 2nd number: (80 ÷ 10) - 1 = 8 - 1 = 7
→ The given 2nd number is 7. The logic holds for the second pair.
Now, let's apply this logic to the given options:
Option 1) (90, 11)
→ 1st number = 90
→ Check 2nd number: (90 ÷ 10) - 1 = 9 - 1 = 8
→ The given 2nd number is 11. Since 8 ≠ 11, this option does NOT follow the logic.
Option 2) (60, 6)
→ 1st number = 60
→ Check 2nd number: (60 ÷ 10) - 1 = 6 - 1 = 5
→ The given 2nd number is 6. Since 5 ≠ 6, this option does NOT follow the logic.
Option 3) (70, 6)
→ 1st number = 70
→ Check 2nd number: (70 ÷ 10) - 1 = 7 - 1 = 6
→ The given 2nd number is 6. This option follows the logic.
Option 4) (100, 11)
→ 1st number = 100
→ Check 2nd number: (100 ÷ 10) - 1 = 10 - 1 = 9
→ The given 2nd number is 11. Since 9 ≠ 11, this option does NOT follow the logic.
Hence, the correct answer is "Option 3".
Number Based Question 4:
In the following triads, each group of letters is related to the subsequent one following a certain logic. Select from the given options, the one that follows the same logic.
BEAN - EBAN - BANE
MAKE - AMKE - MKEA
Answer (Detailed Solution Below)
Number Based Question 4 Detailed Solution
The logic followed here is:
For, BEAN - EBAN - BANE
For, MAKE - AMKE - MKEA
Similarly,
MACK - AMCK - MCKA
Hence, the correct answer "Option 1".
Number Based Question 5:

Similarly, certain mathematical operation(s) on the second number result(s) in the third number and so on. Which of the given options follows the same set of operations as in the given sets? (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 b
e performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) 10 - 20 - 40 - 80 ; 3 - 6 - 12 - 24
Answer (Detailed Solution Below)
Number Based Question 5 Detailed Solution
The logic followed here is:
Logic: Each subsequent number is obtained by multiplying the previous number by 2.
For, (10, 20, 40, 80)
⇒ 10 × 2 = 20.
⇒ 20 × 2 = 40.
⇒ 40 × 2 = 80.
For, (3, 6, 12, 24)
⇒ 3 × 2 = 6.
⇒ 6 × 2 = 12.
⇒ 12 × 2 = 24.
Let's check options one by one:
Option 1) 4 - 8 - 12 - 24
⇒ 4 × 2 = 8. (Matches)
⇒ 8 × 2 = 16 ≠ 12.
Here, logic not followed.
Option 2) 8 - 10 - 20 - 40
⇒ 8 × 2 = 16 ≠ 10.
Here, logic not followed.
Option 3) 6 - 12 - 24 - 48
⇒ 6 × 2 = 12. (Matches)
⇒ 12 × 2 = 24. (Matches)
⇒ 24 × 2 = 48. (Matches)
Here, logic followed.
Option 4) 5 - 10 - 20 - 30
⇒ 5 × 2 = 10. (Matches)
⇒ 10 × 2 = 20. (Matches)
⇒ 20 × 2 = 40 ≠ 30.
Here, logic not followed.
Hence, the correct answer is "Option 3".

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".

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.
