Under the related problems of this chapter, some numbers are given in the examination in one or more shapes or in the form of matrix or equations, which have been arranged according to a certain rule.

Generally these problems are based on a particular rule, so candidates are carefully observing the rules of systemization of numbers to find out what the appropriate number will be in place of the missing post (?)


⇒ Now, please follow the examples of different types (different types) below for clarifying the draft of the questions and the above mentioned facts under this chapter, which is very helpful in solving other questions related to this chapter easily. Will be

 

TYPE 1

Example: What figure would come in place of the question mark (?) in the figure below?

(a) 35 (b) 47 (c) 39 (d) 45

Solution: (c) We carefully observe the above figure
That the middle number in each shape is face-to-face
The sum of the product of the digits is equal to
3 x 4 + 5 x 5 = 12 + 25 = 37
4 x 4 + 7 x 5 = 16 + 35 = 51
Similarly, 3 × 3 + 5 × 6 = 9 + 30 = 39
So in the given third shape, the questionnaire (?) Has the desired number in place of 39.

 

TYPE 2

Example: What’s the number in place of the question mark (?) in the matrix given below?

(a) 4 (b) 6 (c) 8 (d) 10

Solution: (c) In the first two columns of the given matrix, we see that the first and third numbers of each column divided by the second number gets the fourth number,

 

TYPE 3

Example: What number will replace the question mark (?) in the following question?

(a) 47 (b) 64 (c) 81 (d) 121

Solution:(c) of the number on each side of each streak in the figure above,  (6)2 = 36, (7) 2 = 49, (4)2 = 16

Similarly (9)2 = 81 So the questionnaire (?) Is replaced by the appropriate number 81.

 

TYPE 4

Example: In the given figure, what would be the appropriate number instead of the question mark (?)?

(a) 20 (b) 27 (c) 26 (d) 22

Solution: (d) After carefully observing the given figure, we find that the number inside the given circular shape is the sum of the square root of the four numbers outside the shape, such as

So instead of the question mark (?), The appropriate number would be 22.

 

TYPE 5

Example: In the figure given below, what would be the appropriate number instead of the question mark (?)?

(a) 21 (b) 27 (c) 31 (d) 37

Solution: (b) Observe the above figure carefully On observation we find that the number between the digits located on both angles in each shape is the difference of the square of the number on both angles, such as
Figure | In, (9) 2 – (5) 2 = 81-25 = 56
(9) 2 – (8) 2 = 81-64 = 17
(8) 2 – (5) 2 = 64 – 25 = 39

Then the shape || In, (11) 2 – (9) 2 = 121 – 81 = 40
(11) 2 – (8) 2 = 121-64 = 57
(9) 2 – (8) 2 = 81-64 = 17

Similar shape ||| In, (7) 2 – (3) 2 = 49 – 9 = 40
(6) 2 – (3) 2 = 36 – 9 = 27
(7) 2 – (6) 2 = 49-36 = 13
Hence the appropriate number ’27’ will be in place of the question mark (?).

 

TYPE 6

Example: In the given figure, what would be the appropriate number in place of the question mark (?)?

(a) 39 (b) 42 (c) 48 (d) 56

Solution: (b) After carefully observing the given figure we find that the number located in each corner of the square shape, the difference between the two numbers used in the semi-circular shape
Three times, like –
(30-12) x 3 = 18×3 = 54
(30-13) × 3 = 17 × 3 = 51
(27-12) x3 = 15×3 = 45
Similarly, (27 – 13) x 3 = 1.4 x 3 = 42
Hence the appropriate number = 42 instead of the question mark (?)

 

TYPE 7

Example: In the figure given below, which number would be replaced by the question mark (?)?

(a) 8 (b) 11 (c) 6 (d) 7

Solution: (c) In the above figure, we see that the numbers used in the shape of the triangle in each shape, obtained by dividing the number used in the first square measure of the first two square shapes, decreased the number used in the third square shape Which is expressed as follows
3 x 4 – 5 – 12 – 5 – 7
7 x 3- 9 – 21 – 9 – 12
Similarly, 4 × 2 – 2 = 8 – 2 = 6
So the appropriate number of question marks (?) Will be ‘6’.

 

TYPE 8

Example: If 9 × 3 + 8 = 24,10 × 2 + 7 = 35 and 80 × 40 + 3 = 6, then 12 x 4 + 3 =?

(a) 7 (b) 9 (c) 12 (d) 16

Solution: (b) After carefully observing the given equation, we find that by solving the mathematical symbol ‘×’ in ‘÷’ and solving the mathematical symbol ‘+’ in ‘× The intended value has been received. It has been solved as follows
9×3 + 8 = 9 ÷3×8 = 24
10 × 2 + 7 = 10 ÷2 × 7 = 35
80 Χ 40 + 3 = 80 ÷40×3 = 6
Similarly, 12 × 4 + 3 = 12 ÷ 4 × 3 = 9
So the appropriate number ‘9’ in place of the question mark (?)

 

TYPE 9

Example: In the figure given below, what number will replace the question mark (?)?

(a) 161 (b) 157 (c) 167 (d) 162

Solution: (c) After carefully observing the given figure, we find that the bottom number in each figure, multiplied by the middle number in the sum of the two numbers at the top, Is obtained by adding, like
(8 + 9) x 6 + 6 = 17 x 6 + 6 = 102 + 6 = 108
(7 + 8) x 5 + 6 = 15 x 5 + 6 = 75 + 6 = 81

Similarly, (12 + 11) x 7 + 6 = 23 x 7 + 6 = 161 + 6 = 167

So the intended number of the question mark (?) To come in = 167

 

TYPE 10

Example: Select the appropriate letter in place of the question mark (?) in the matrix given below.

(a) JI (b) HS (c) KT (d) AD

Solution: (b) A given matrix On the study we find that each letter used in it is contrary to each other in the English alphabet, along with the first letter rising sequence in each column and the second letter in descending order.

So the appropriate letter group ‘HS’ will be in place of the question mark (?).

TYPE 11

Example: With the help of the options given below, select the appropriate number to replace the question mark (?).
FED x 3 = 1629

BCD x 4 = 492

BEF x 1 =?

(a) 451 (b) 145 (c) 514 (d) 415

Solution: (b) After carefully observing the given equation given above, we find that given the number given in the alphabetical group of each equation, the number of each in the alphabetical serial value is decreased. The number obtained by multiplying the number is obtained, such as

Hence the appropriate number ‘145’ in place of the question mark (?).

 

 

TYPE 12

Example: In the matrix given below, select the appropriate letter-number that comes in place of the question mark (?) in the first row, with the given options.

(a) NP24 (b) QT40 (c) NP40 (d)PO68

Solution: (c) The first letter in each line is the letter located three places ahead of the English alphabet, while the second letter is also the letter located three places ahead. The second number in each row is already 2 more, while the third number has been multiplied by 2 times.
