Ten most important questions of Reasoning Analogy in missing numbers in various figures

 we are going to discuss Ten most important  questions of Reasoning Analogy in missing numbers in various figures

PROBLEM # 1
                  Find missing Number ?

10 most tricky puzzle with their solutions
Since in 1st row we can write 2,3 and 4 these numbers to get 10 like this
 ( 3 × 2 ) + 4 = 6 + 4  = 10
And in 2nd row  ( 4 × 3 ) + 5 = 12 + 5 = 17, 
In 3rd row ( 5 × 4 ) + 6 = 20 + 6 = 26
Similarly ( 6 × 5 ) + 7 = 30 + 7 = 37
So  " ? "   Will be replaced by 37 .
 पहली संख्या को दूसरी संख्या से गुणा करने   के बाद उसमें तीसरी संख्या जोड़ देने से हमें    बराबर है  चिन्ह के दायीं  तरफ की संख्या मिलती है

                   PROBLEM # 2

               Find missing Number ?


                         10 most tricky puzzle with their solutions
Let us find relation between 3 and 32 , if we double the square of  3 ,we shall have 18. 
2 × ( 3^2) = 2 × 9 = 18
And in 2nd row if we double the square of  4 ,we shall have 32
2 × ( 4^2) = 2 × 16 = 32
In the same way third ,fourth and  fifth column can be calculated like this 

          2 × ( 5^2) = 2 × 25 = 50
          2 × ( 6^2) = 2 × 36 = 72
          2 × (7^2)  = 2 × 49 = 98
So 98 is required answer.
 सबसे पहले जो संख्या दी गई है उसका वर्ग करें और उसको 2 से गुणा कर दीजिए हमें दाएं तरफ की संख्या मिल जाएगी ।


                PROBLEM # 3



           Find missing Number ?



As the sum of first and second number in first and second rows in any particular column is equal to third element in that particular column so to get the value of " ? " . Add first and second numbers column wise to get third number as follows.
56 - 12 =  44,
78 - 30 = 48 ,
65 - ? = 14 ➡️  ? = ? = 65 - 14  = 49 
So 49 is required number .
इस   प्रश्न को हल करने के लिए हम columnwise  सोचेंगे । हम हर कोल्लम है पहली संख्या से दूसरी संख्या को घटाकर तीसरी संख्या प्राप्त कर सकते हैं जैसे कि 
56 - 12 = 44 ,
78 - 30 = 48 , इसी तरह से
 65 - 51  = 14

                    PROBLEM # 4
              Find missing Number ?

10 most tricky puzzle with their solutions

Answer can be splited into two parts, 1st part can be obtained multiplying given two  numbers and second part can be obtained by adding these two numbers .
1st row 5 × 3  = 15 and 5 + 3 = 8 so 5 + 3 = 158
2nd row 9 × 1  = 9 and 9 + 1 = 10 so 5 + 3 = 910
3rd  row 8 × 6  = 48 and  8 +6 =14  so 8 + 6 = 4814
4th row 4 × 4 = 16 and   4 + 4 =8 so  4 + 4 = 168.
5th row 7 × 3 = 21 and 7 + 3 = 10 so 7 + 3 = 2110
So ?  Will be replaced by 2110.
 हमारे पास दो संख्याएं दी गई है पहले उन दोनों संख्याओं को गुणा करेंगे तो दाएं तरफ की संख्या के पहले दो अंक (  अगर गुणा करने से 2 अंक बनते हो तो) लिखे जाएंगे फिर उन दोनों संख्याओं को जमा करेंगे तो दाएं और दी गई संख्या के आखिरी दो अंक लिखे जाएंगे ।
 .
PROBLEM # 5
Find missing Number ?


Formula a*b = (a × b) + (b - 1)

This the sum of two numbers , out of 1st number is product of two given two numbers and second number is the number one less than 2nd given number

       3*2 = (3 × 2) + (2 - 1) = 6 + 1 = 7
5*4 = (5 × 4) + (4 - 1) = 20 + 3 = 23
7*6 = (7 × 6) + (6 - 1) = 42 + 5 = 47
9*8 = (9 × 8) + (8 - 1) = 72 + 7 = 79
10*9 =(10 × 9) + (9 - 1) =90 +8 = 98
पहले दोनों दी गई संख्याओं को गुणा करें फिर दूसरी संख्या से एक घटाने के बाद गुणा करने के बाद जो उत्तर आया था उसमें जमा कर दें आपको  दाएं तरफ  की संख्या मिल जाऐगी ।

                      PROBLEM # 6
                   Find missing Number ?



Suppose we have three numbers a , b and c then

Formula for this puzzle is = a × b + b or  b(a + 1)

Put a = 2 and  b = 6 in above formula ,we get

1st Line = (2  × 6)   +  6  = 12   +   6   = 18
Put a = 4 and  b = 20 in above formula to get 2nd line,we get
(4  × 20) + 20 = 80   +  20  = 100
Put a = 5 and  b = 21 in above formula to get 3rd line,we get
(6 × 21) + 21 = 126 +  21  = 147
So required and correct answer will be  6
तीसरे स्थान पर दी गई संख्या को दूसरे स्थान  पर दी गई संख्या से भाग करें तथा जो उत्तर आएगा उसमें से  एक  घटाएं करें हमें पहले स्थान पर दी गई संख्या मिल जाएगी

                       PROBLEM # 7
Find missing Number ?


10 most tricky puzzle with their solutions

If in every row ,we add 1st and 3rd column and then multiply the sum with 2ndcolumn ,we shall have number in 5th column .

If we  consider three numbers a , b and c and start calculation by   Formula =  (a × b) + (b × c)  or b(a + c)  --------(1)

To get 1st line , put a = 1 , b = 2 and c = 3 in (1) , we get 

1st Line =  (1×2) + (2×3) =2 + 6 = 8

To get 2nd line , put a = 2 , b = 3 and c = 4 in (1) , we get 

2nd  Line =  (2×3) + (3×4) = 6 + 12 =  18

To get 3rd line , put a = 3 , b = 4 and c = 5 in (1) , we get 

3rd Line =  (3×4) + (4×5) = 12 + 20  = 32

To get 4th line , put a = 4 , b = 5 and c = 6 in (1) , we get 

4th Line =  (4×5) + (5×6) = 20 + 30  = 50

Similarly Last line can be calculated by putting a = 5 , b = 6 and c = 7 in (1) , we get 

Last line  =  (5×6) + (6×7) = 30 + 42  = 72
Hence Required  and correct answer will be 72
पहले दूसरे column  ब  दूसरे तीसरे column को आपस में गुणा करें , गुणा करने के बाद जो उत्तर आऐंगे  उनको जमा कर दें हमें चौथे column की संख्या मिल जाएगी ।

                 PROBLEM # 8
             Find missing Number ?





Case 1


If we choose   1st Line  from 5 then look at the pattern  line wise 
                              5  ×  3 = 15
               8  ×  3 = 24
               12 × 3  =  36

In this pattern we can conclude 12 ×3 = 36

Case 2

If we choose   1st Line  from ? then look at the pattern  line wise

                               ?    ×  3 = 12
                 5   ×  3  = 15
                    8   ×  3  = 24   
Therefore ? will be replaced  by 4.
Hence    4 ×  3  = 12

  PROBLEM # 9
Find missing Number ?

This circle can be divided into two parts ,  1st part containing the number 4 ,5 ,6 and 7 and second part containing 7 , 9 ,11 and ?.            Now study  the opposite number of 4  which is 7 . Then study the relation between other numbers and its opposite number ,we find difference between 4 and 7 is 3 , difference between 5 and 9 is 4 , difference between 6 and 11 is 5  . so in this pattern we find difference between ' ? '  and  7 must be 6 . 
 7 - ? =  2 means ? = 5
 7 - 4 =  3
 9 - 5 =  4
11 - 6 = 5 , the difference is increased by 1 everytime .
 ?   - 7 = 6  means ? = 13
Either 5 or 13 should be the required number, but 5 is not given in any option.
So ? Will be replaced by 13 which is the required answer 
Hence  option ( b)  is the correct option

PROBLEM # 10
                     Find missing Number ?

We shall try every possible relation between different numbers given either rowwise or columnwise . It is found that there is no relation if we consider First row . 
 After elemination 1st row we can develop a relation between 2nd ,3rd and 4th row which is multiplying the 2nd and 3rd numbers then double it to get 4th number columnwise .
 2 × (7 × 4 ) = 2 × 28 = 56
2 × ( 15 × 6 ) = 2 × 90 = 180
2  × ( 8 ×  ?  ) = 80 
So ? = 5
So correct options will be  (d ) 5.

Ten most important problems of missing numbers in Reasoning Analogy part 2



Let us discuss series of missing numbers and missing terms and their  solutions in reasoning analogy .

Problem # 1

This series consists of two alternate series 1st series consist of number 1,3, 5 and 7 and second series consist of  the series 2 ,5 ,8,?

So in 1st series there is difference of 2, so next number in the series must be 2 greater than 7 that is 9 .
In the 2nd series  we observed a difference of 3 show the next number must be 11 that is 3 greater than 8 the last term therefore the last two terms of the series 11 and 9

The correct option is  ( a ) 11,9

Problem # 2

Find the next number? 

This series is also the combination of two series one with the number  2, 48 ,16 ,32 and second series consist of these numbers 6, 9 13 ,18 ,?  . So ? Will be filled out using 2nd series not from 1st series.

Observing 2nd series carefully ,In  second series numbers are increased by  3 ,4 and 5 ,so next Increment should be of 6. This implies next number should be  24 with an increment of 6.

The correct option is  ( a ) 

Problem # 3


Observe carefully all the numbers in the series are prime number , so  next prime number after 37 will be 41 .This implies that  ?  will be replaced by 41.

The correct option is  ( c ) 

Problem # 4

which is wrong number  ?

All the numbers in this series are consist of three digits numbers and Middle digit is the sum of first and last digit in all the numbers except one that is 342 in this case 3 + 2 is equal to 5 not equal to 4 .So  correct option is option is  (c) ,this is the wrong number in the series .

The correct option is  ( C ) 

Problem # 5

Every number in this series is the sum of its two  preceding number plus 3.

14  = ( 7 + 4 ) + 3
24 = ( 14 + 7 ) + 3
41 = ( 24  +14 ) + 3
?   = ( 41 + 24 ) + 3 = 65+3 = 68

The correct option is  (  C ) 

Problem # 6

Which is wrong number  ?

This series consists of triplet ,that is every third number is product  its two preceding numbers

  As third  number 10 is the product of 2 and 5, sixth number  18 is the product of fourth (3) and fifth (6 ) numbers .

So ninth number of the series  must be the product of seventh and  eighth numbers. 4 × 7 = 28 instead of 30 

The correct option is  ( C ) 

Problem # 7


Find the next number? 

Here second  number is the sum of the digits of first number the forth number is the sum of digits of third number similarly every even positioned number is  the sum of its preceding number's digits question  mark will be replaced by the sum of 5 + 3 that is 8

The correct option is  ( a ) 

Problem # 8

Find the next number? 

Writing 3 = 2² - 1

Writing 8 = 3² - 1

Writing  15 = 4² - 1

Writing 24 = 5² - 1


Show next number should be  6² - 1 ( square minus 1 ) that is 35

Writing  6² - 1 = 35

The correct option is  (2 ) 

Problem # 9

Which is wrong  number? 

Every number in this series is the double of its preceding number

 So double of 1 is   2 , double of 2 is 4 ,double of 4 should be 8 ( instead of 7 ) , double of 8 is 16 and double of 16 should be 32 .  So 7 is the wrong number in this series.

The correct option is  ( 1 ) 

Problem # 10

Find the next number? 

In the series every number is the the cube of its  position plus 1 .

Since

  2 =  1³ + 1

   9 =  2³ + 1

  28 =  3³ + 1

  65  =  4³ + 1

  126 =  5³ + 1

  In the same way next number of the series must be  6³ + 1 = 216 + 1 = 217

The correct option is  ( 1 )

Twelve Most Interesting figures problems of Reasoning analogy part 3

Discussed the most important  reasoning analogy problems and frequently asked picture problems in previous competitive  examinations along with their answers .
Post your answer in comments and to confirm your answer click here.


If square root of any number is added /subtracted infinite time ,then what will be the answers .



Problem # 1


(a) 5        (b) 25            (c) 3             (d) 49


Outermost numbers are the  product of Square roots of two  numbers attached to it.

Since 14 is attached with 4 and 49 , the square root of 4 and 49 are 2 and 7 respectively now multiplying 2 and 7 to get 14.

Since 12 is attached 
with 36 and 4 , the square root of 36 and 4 are 6 and 2 respectively now multiplying 6 and  2  t get 12.

So 30 must be the product Square Root  of 36  and ? , so if we put 25 instead of Question Mark   ? .Then product of square root of 25 and the square root of 36 which will be  equal to 30.

Similarly product of square root of  49 and Square Root of ? must be equal to 12 . So we had already put 25 in place of ? to give product 35 .

Hence  (b) 25  is right option.

Problem # 2


Starting from 3 and moving clockwise multiply 3 with 2 and subtracting 1 from it  to get 5 .
Multiplying 5 with 2 and subtracting 3 from result so obtained to get 8. 
Multiplying 8 with 2 and subtracting 2 from it to get 13.
 Now multiplying 13 with 2 and then subtracting 4 from  result so obtained to get 22.
At last multiplying 22 with 2 then subtracting 5 from the result so obtained to get 39 .
so (c) 39 is the right answer

Problem # 3


1st Step 

In  1st Row B ,D are F are written in a  gap of one letter .
In 3rd Row N ,P and R are written in a gap of one letter
In 2nd Row H and J are also written in a gap of one letter ,So J and ? must be written with a gap of one letter .This means after J the Lett with one gap will be L.

2nd Step 

In 1st row  digits associated are 3 ,3 and 6 means last digit in the Row is sum of 1st two digits 3+3 = 6.
In 3rd row  digits associated are 7 ,9  and 16 means last digit in this Row is sum of 1st two digits 7+9 = 16.
In 2nd  row  digits associated are 5 ,6 and ? will be replaced by sum of other two digits 5+6 = 11 .

So (a) L11 is the right option

                

Problem # 4


 Here in this Figure  result will  be calculated column wise in any particular column. In first column the fourth element is calculated by dividing second element with third  element and then multiplying first and the results so obtained.

Problem # 5


Add all the numbers in any particular figure and then subtract 2 from it to get the middle number .

In figure number 1 we have 0 + 6 + 4 + 2 = 12 minus 2 = 10 { middle number }
In figure second 6 + 2 + 10 + 8 = 26 - 2  = 24 .
Similarly In figure 3  we have 4 + 14 + 12 + 10 = 40 - 2 = 38 ( Question Mark )  which is are required number. 

Therefore option ( C ) is  right  answer .

Problem # 6



If we add all the numbers column wise then we get 99 in all the three columns so we shall  have 42 in place of question mark to  have total   99 in all the three in first column .
Because 40 + 24 + 35 = 99
In second column we have 30 + 35 + 34 = 99 . While in last column when we add ? + 30  +27 the sum will be 99 so desired number  will be 42.
The right option is ( a) 42

                    

Problem # 7


Find the sum of numbers which are in the Row ( horizontal ) then subtract this total from the sum which are in column ( vertical ) to find the number which is in the middle of the given figure .
In figure I  5 + 6 is equal to 11 and  4 + 7 which is also equal to 11 so difference of both the  sum is equal to zero which is the middle number

In figure II  7 + 6 is equal to 13 an  8+ 4 which is also equal to 12 so difference of both the  sum is equal to  13  - 12 1which is the middle number

In figure III  11 + 2 is equal to 13 and  0 + 2 which is also equal to  2 so difference of both the  sum is equal to  13 - 0 = 11 which will be the middle number.
        Correct option is c(11)
          

Problem # 8


Multiplying all the elements in 2nd row with 2 then add elements of 1st and 2nd row downward to get the elements in  3rd row
1st Column.    13  + ( 7×2 ) = 13 + 14 = 27
2nd Column 54 + (45 × 2)  = 54 + 90 = 144
3rd Column   ? + (2× 32) = 68
This implies ? = 68 - 64 = 4 
So (4) is right option .

Problem # 9


(a) 15       (b) 12          (c) 18       

   (d) 49


To find the middle number in each figure add all the numbers except middle number then divide it with 4 to  get middle number .

In figure 1 add 24 + 32 + 40 + 36 = 132 which  when divided by 4 gives 33 

In figure II add the numbers  27 +19 +  20 + 22 = 88 Which when divided by 4 gives 22 

similarly in III  figure when we add all the numbers 6 + 16 + 14 + 1 2 = 48 which is when divided by 4  gives 12 
,So option   ( b ) is right option

                       

Problem # 10


Sum of all the digits of 1st and 2nd rows are 17 .Similarly sum of all digits of 3rd row must be 4 +7 + ? = 17 .This implies  the value of  ? should be 6.
Hence the correct  option will be  ( a ) 6

Problem # 11



Spilt this circle into two parts ,one above x axis and other below x axis , the sum of digits in both the semi circle must be equal to each  other . 
This means ? + 4 + 5 + 6 = 11 + 9 + 3+7
? +15  = 30
? = 15
So option ( d ) 15 will be right option

Problem # 12


This series consists of two series of alternative numbers ,first one consists of 2, 4, 8, 16,32 so on and second series consists of the number 6, 9, 13, 18, so on .
 So our next number in the given series will be derived from the second series, .6, 9, 13, 18, so on .
Look at the difference between first two number 6 and 9 which is equal to 3 ,And  difference between second number (9) and third number (13 ) in 2nd series is 4 And  difference between third number ( 13 ) and fourth number ( 18 ) in the second series is 5 so difference between 18 and next number must be 6 it  means next number must be 24 because 24-18 = 6
Show the right option is option (a)

Ten most important questions of Reasoning Analogy in missing numbers in various figures


Ten most Important questions of Reasoning Analogy of missing numbers have been discussed with their Solutions in an easy manners.

 Problem #1 

 

Moving clock wise from top right number , Double the top right number to get bottom right number and add 2 to get bottom left number, now again double this number to get top left number in all the three figures .

Hence in  option (4)  24  is right answer

    Problem # 2

Multiply  all the numbers which are on the corners of the given triangles to get the number which is on the centre of particular triangle.
In 1st triangle  multiply all the numbers on the corner of triangle
1 × 2 × 3 = 6
Again In 2nd  triangle  multiply all the numbers on the corner of triangle
2 × 5 × 3 = 30
Similarly In 3rd  triangle  multiply all the numbers on the corner of triangle
4 × 8 × 5 = 160

Hence in  option (3)  160  is right answer

Problem #  3

If we add the top and bottom  numbers and the subtract from it the sum of left  and right  terms we shall get the middle number in all the figures.
in 1st figure
(3+7) - (2+5) = 3 
In 2nd figure
(9+9) - (7+8) =3
In 3rd figure 
(8+8) - (6+6) =6

Hence in  option (4) 6 is right answer

Problem # 4

Multiply the top numbers and bottom numbers row wise the take the difference  of it .
In 1st figure 
(5×6) - (3×8) = 30 - 18 =6

2nd figure
(10×4) - (2×7) = 40 - 14 =26

3rd figure 
(9×7) - (6×8) = 63 - 48 = 15

Hence in  option (2)  15  is right answer

Problem # 5



Cross multiply the numbers to get middle number in all the figures .

In 1st figure
12 × 5 = 15 × 4 = 60 


In 2nd figure
3 × 14 = 6 × 7 = 42

In 3rd figure
26 × 3 = 13 × 3 = 78

Hence in  option (3)  78 is right answer

Problem # 6

Take cube roots of all the numbers which are on outer side 
 all the ellipse ( given figure ) and then add these numbers  to get middle number in the figure .



In 1st figure  cube roots of 1, 64, 27 and 8 are 1 , 4 , 3 and 2 respectively. 

Now add these numbers. i.e 1 + 4 +3 +2 = 10
In 2nd figure  cube roots of 8, 125, 64 and 27  are 2 , 5 , 4 and 3 respectively. 

Now add these numbers. i.e 2 +5 + 4 +3 = 14
Similarly In 3rd figure  cube roots of  27 , 216 , 125 and 64 are 3 , 6 , 5 and 4 respectively. 
Now add these numbers. i.e 3 + 6 + 5 + 4 = 18


Hence in  option (4)  18  is right answer

Problem # 7


In the all the figure add both numbers which are 2nd and 3rd columns then multiply in this result with the number which is on the right side of given figure to get the number on the left side of given figure.
In 1st figure 1 + 2 =》3 × 9 = 27
In 2nd figure  2 + 3  =》 5 × 7  = 35
In 3rd  figure  x + 4  =》 (x+4) × 4 = 36
 4x × 16 = 36
 4x= 36 - 16 =20
x = 5

Hence in  option (3)  5  is right answer

Problem # 8

(1)  64   (2)  31 (3)  93  (4)  27

1st Figure


 From 1st figure we can see that lower number is thrice (3 times) of sum ( addition ) of both numbers which are on upper portion of figure i. e . 18 + 9 = 27 .
Now multiply it with 3 , we get 27 ×3  =81 , which is the lower number in 1st figure.

3rd Figure

And for third  figure add both the numbers 24 and 7 and then multiply  the sum with 3 like this 24 + 7 = 31 and 31 × 3 = 93

2nd  Figure

Similarly ?  in 2nd figure can be found by adding 23 and 8 and then Multiply  it with 3 as follows 

     23 +8 =31 × 3 =93 , Hence 93 is the required number.

Hence in  option (3)  93  is right answer

Problem # 9

From 1st two  figures if we multiply top and bottom terms and then subtract  the result of product of left and right terms from it we shall get the number in the middle of the circles in both the given figures.
6×7 - 4×5 = 20 in 1st Figure
9×7 - 6×3 = 45
Similarly middle number of 3rd figure can be calculated as follows
8×8 - 4×6 = 40

Hence in  option (3)  40  is right answer

Problem # 10



If we add the left and right  numbers and the subtract from it the sum of top and bottom  terms we shall get the middle number in all the figures
(5+6 ) - (4+7) = 0
(7+6 ) - ( 8+4 ) = 1
similarly 3rd term can be calculated as follows
( 11+2 ) - ( 0 +2) = 11

Hence in  option (3)  11  is right answer
