Missing Number in Diagram MCQ Quiz - Objective Question with Answer for Missing Number in Diagram - Download Free PDF

The logic follows here is:

Pattern: Square of the bottom number = Sum of the top number.

In the first diagam:

(12)² = 80 + 64

144 = 144.

In the second diagam:

(16)² = 120 + 136

256 = 256

Similarly, In the third diagam:

(?)² = 90 + 31

(?)² = 121

? = √ 121

? = 11

Hence, the correct answer is "11".

Logic follows here is:

LOGIC: Multiplication of bottom Numbers + Top Number = Middle Number

In the first Figure:

(7 × 5) + 6 = 41

In the second Figure:

(9 × 7) + 8 = 71

In the third Figure:

(11 × 9) + 10 = 109

Hence, "71" is the correct answer.

The logic is:

First diagram:

⇒  (12 + 18 + 30) ÷ 10

⇒ (60) ÷ 10

⇒ 6

Second diagram:

⇒ (16 + 24 + 40) ÷ 10

⇒ (80) ÷ 10

⇒ 8

Similarly,

Third diagram: 

⇒ (45 + 18 + 27) ÷ 10

⇒ (90) ÷ 10

⇒ 9

Hence, '9' is the correct answer.

The Logic follows here is;

In Figure 1:

In Figure 2:

Similarly;

In Figure 3:

Hence, "125" is the correct answer.

The logic is:

Starting from 1 in clockwise direction.

1 + 2 = 3

2 + 3 = 5 

3 + 5 = 8 

Similarly,

5 + 8 = 13

Hence, 13 is the correct answer.

The logic followed here is:

Top Number 48:

Top number 63:

Similarly,

Top number 56:

Middle number (?) = 21.

Hence, the correct answer is "21".

The pattern followed here is:

11 → 1³ = 1

28 → 2³ = 8

327 → 3³ = 27

? → 4³ = 64

? = 464

5125 → 5³ = 125

Hence, ‘464’ is the correct answer.

The logic follows here is: Cross relation,

Figure (1) → 10 × 8 = 80

Figure (2) → 9 × 7 = 63

Similarly,

Figure (3) → 8 × 6 = 48

implies, ? = 8

Hence, 8 is the correct answer.

The logic followed here is:

Logic: Sum of all the numbers = 100

38 + 56 + 6 = 100;

38 + 16 + 46 = 100;

Similarly,

55 + 43 + ? = 100

98 + ? = 100

? = 100 - 98 = 2

The logic followed here is;

Logic: Difference of the top numbers × 4 = Bottom Number.

Now, checking the figures:

 → (6 - 2) × 4 → 4 × 4 = 16.

 → (5 - 4) × 4 → 1 × 4 = 4.

 → (7 - 2) × 4 → 5 × 4 = 20.

 → (5 - 3) × 4 → 2 × 4 = 8.

 → (8 - 5) × 4 → 3 × 4 = 12.

Hence, the correct answer is "Option 4".

The logic followed is:

(Addition of left and right side number) × (Difference between lower and upper number) = Middle number

Figure 1:

⇒ (3 + 4) × (8 - 6) = 7 × 2 = 14 (Middle number)  

Figure 2:

⇒ (6 + 3) × (9 - 2) = 9 × 7 = 63 (Middle number)  

Similarly, 

Figure 3:

⇒ (4 + ?) × (6 - 3) = 36

⇒ (4 + ?) × 3 = 36 

⇒ (4 + ?) = 12

⇒ ? = 12 - 4

? = 8

Hence, the correct answer is "8".

Given number follow a pattern

So, 1 is the missing number.

Hence, "1" is the correct answer.

Logic:

Thus, 176 is the missing number.

The logic followed here is-

Hence, 'option 3' is the correct answer.

The logic follows here is;

Divide the figure into three parts:

In part 1:

Middle Number = (Left + Right)/ 2

Middle Number = (5 + 7)/ 2 =  12/ 2 = 6

In part 2:

Middle Number = (Left Numbers + Right Numbers)/ 2

Middle Number = (5 + 4 + 4 + 7)/ 2 = 20/ 2 = 10

In part 3:

Middle Number = (Left + Right)/ 2 

Middle Number = (3 + 3)/ 2 = 6/ 2 = 3

Hence, "3" is the correct answer.
