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

The logic is:

1^st figure: 0 + 6 + 4 + 2 = 12 and 12 – 2 = 10 → number at the centre of the figure.

2^nd figure: 6 + 2 + 10 + 8 = 26 and 26 – 2 = 24 → number at the centre of the figure.

Similarly,

3^rd figure: 4 + 14 + 12 + 10 = 40 and 40 – 2 = 38 → number at the centre of the figure.

The pattern follows here is,

1^st image: 2 × 3 = 6 and 6 + 8 + 10 = 24

2^nd image: 5 × 7 = 35 and 35 + 15 + 2 = 52

Similarly,

3^rd image: 10 × 12 = 120 and 120 + 3 + 15 = 138

Hence, 138 is the correct answer.

The pattern followed in the given series:

When we consider the rows we can see that there is a pattern that repeats in every row,

• There are three colors of flags namely, red, blue & black.
• Each flag consists of a triangle that is above the flag, inside the flag, or below the flag.​

Now we consider the third row:

• Here a black flag is missing
• A flag with a triangle above the flag is missing.

​
Now we consider the given options:

Option 1) The flag must be black & the triangle should be above.

Option 2) The flag must be black.

Option 3) The triangle should be above.

Option 4) The pattern is correct.

Hence, the correct answer is "Option 4".

The logic followed here is:

Logic: Square of the sum of upper number = lower number.

→ 4² + 5²  = 41

= 16 + 25 = 41.

→ 32 + 62  = 45

= 9 + 36 = 45.

Similarly,

→ 22 + 72  = ?

= 4 + 49 = 53.

Hence, the correct answer is "Option 3".

The logic followed here is,

Logic: centre number = sum of outer number - 2

For, 

→ (2 + 4 + 6 + 0) - 2 = 10

For, 

→ (6 + 2 + 8 + 10) - 2 = 24

Similarly, for 

→ (10 + 12 + 4 + 14) - 2 = 38

Hence, the correct answer is "Option 3".

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 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 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 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.
