Latest Number Based MCQ Objective Questions
Number Based Question 1:
Select the option at the place of (?) that is related to the third number in the same way as the second number is related to the first number.
12: 60 :: 16 : ?
Answer (Detailed Solution Below)
Number Based Question 1 Detailed Solution
The logic followed here is:
Logic: Second number = First number x (First number / 2 - 1).
Now,
For, 12 : 60
⇒ 12 x (12 / 2 - 1) = 12 x (6 - 1) = 12 x 5 = 60.
Similarly, for 16 ∶ ?
⇒ 16 x (16 / 2 - 1) = 16 x (8 - 1) = 16 x 7 = 112.
Hence, the correct answer is "Option 1".
Number Based Question 2:
2 : 11 :: 3 : ________
Answer (Detailed Solution Below)
Number Based Question 2 Detailed Solution
The logic followed here is:
2 : 11
23 + 3 = 11
8 + 3 = 11
11 = 11 (LHS = RHS)
Similarly,
3 : __
33 + 3 = ?
27 + 3 = ?
30 = ?
Hence, "Option 1" is the correct answer.
Number Based Question 3:
Select the option that is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term.
21: 196: : 29:? :: 38 : 315
Answer (Detailed Solution Below)
Number Based Question 3 Detailed Solution
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.
Number Based Question 4:
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 the fourth number is related to the third number.
7 : 13 :: 16 : 31 :: 46 : ?
Answer (Detailed Solution Below)
Number Based Question 4 Detailed Solution
Logic : First number × 2 → A - 1 = Second number
7 : 13 → 7 × 2 ⇒ 14 - 1 = 13
16 : 31 → 16 × 2 ⇒ 32 - 1 = 31
Similarly,
46 : 91 → 46 × 2 ⇒ 92 - 1 = 91
Hence, the correct answer is "Option 3".
Number Based Question 5:
Select the option that is related to the third number in the same way as the second number is related to the first number.
121 : 9 :: 256 : ?
Answer (Detailed Solution Below)
Number Based Question 5 Detailed Solution
The logic followed here is:
Logic: (√1st number) - 2 = 2nd number.
For, 121 : 9
⇒ (√121) - 2 = 9
⇒ 11 - 2 = 9.
Similarly,
256 : ?
⇒ (√256) - 2 = 9
⇒ 16 - 2 = 14.
Hence, the correct answer is "Option 2".

(121, 81, 2)
(88, 54, 2)
Answer (Detailed Solution Below)
Number Based Question 6 Detailed Solution
Download Solution PDFGiven:
(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)".
Study the given pattern carefully and select the number that can replace the question mark (?) in it.

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.

(15, 21, 10)
(25, 36,17)
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".

(82, 35, 78)
(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 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.

(16, 10, 131)
Answer (Detailed Solution Below)
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.
