# Missing numbers in figures

1. In the given below find the value of ‘?’.
A) 19      B) 20      C) 18      D) 13

Explanation: In this figure, as the numbers are given in the form of a circle look out for a clockwise  or anticlockwise direction. Here, start at 3 and see the numbers after every two spaces in the clockwise direction. You will notice a series forming. Just add three to all the numbers and you will get that number after two spaces. Thus in place of ?, 18 will be the number. Because when you add 3 to 15 you will get 18. So, the correct answer is C.

Ans: C

2. In the following question, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character accordingly.

A) 166         B) 170      C) 184       D) 172

Explanation: Clearly, (1st row)2 + (2nd row)2 + (3rd row)2 = 4th row.
Thus in the first column, 52 + 22 + 62 = 65
In the second column, 42 + 72 + 32 = 74
In the third column, missing number = 82 + 52 + 92 = 170

Ans: B

3. Find the missing character in the following questions.
A) 380        B) 624      C) 560       D) 475

Explanation: Clearly, we have
(2 × 6) + 1 = 13
(13 × 6) + 1 = 79
(79 × 6) + 1 = 475
So, missing number is 475.

Ans: D

4. Find the missing character in the following questions.
A) 62        B) 64      C) 60      D) 68

Explanation: Clearly, we have
6 × 2 + 2 = 14
14 × 2 + 2 = 30 and so on
So, missing number is 30 × 2 + 2 = 62

Ans: A

Explanation: In the first column,
18 − 12 = 6; 26 − 20 = 6
In the second column,13 − 7 = 6; 35 − 29 = 6
In the third column, 19 − 13 = 6; 20 − 14 = 6

Ans: C

7. In the following question, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character accordingly.
A) 28       B) 22           C) 16           D) 18

Explanation: In the first row,
6 × 3 = 18; 8 × 3 = 24
In the second row, 3 × 9 = 27; 5 × 9 = 45
In the third row, 8 × 6 = 48 
∴ Missing number is 3 × 6 = 18

Ans: D

8. In the following question, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character
accordingly.
A) 11         B) 7         C) 8            D) 19

Explanation: Clearly, sum of numbers in each row is 20.
So, missing number is 20 − (5 + 8) = 7

Ans: B

9. In the following question, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character accordingly.
A) 5           B) 8          C) 6         D) 4

Explanation: Clearly,
(1st row) × (2nd row) × (3rd row) = 4th row.
In the first column, 5 × 4 × 3 = 60
In the second column, 5 × 6 × 4 = 120
Let the missing number in the third column be x.
Then, 7 × 4 × x = 140
28 × x = 140 Þ x = 140/28 Þ x = 5

Ans: A

10. In the following question, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character accordingly.
A) 2           B) 5            C) 4           D) 3

Explanation: In the first row,
( 6 + 8 + 5) − (7 + 6 + 2) = 4
In the second row, missing number is
(4 + 3 + 6) − (2 + 3 + 4) = 13 − 9 = 4.

Ans: C

11. In the following question, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character accordingly.
A) 36, 10        B) 49, 12      C) 36, 12            D) 49, 10
Explanation: The numbers in the first row form a series 32, 42, 52. So, missing number in the first row is 62 = 36
The numbers in the second row form the series

3, 4, 5, 6.
The numbers in the third row form the series
3, 6, 9
So, missing number in the third row is 9 + 3 = 12

Ans: C12. In the following question, a matrix of certain

A) 251            B) 263            C) 247           D) 236

Explanation: Clearly, (1st row)3 + (2nd row)3 + (3rd row)3 = 4th row.
So, in the first column,
43 + 33 + 53 = 64 + 27 + 125 = 216
In the third column,
73 + 23 + 53 = 343 + 8 + 125 = 476
In the second column, missing number is
23 + 63 + 33 = 8 + 216 + 27 = 251

Ans: A
