Ten Figure problems in reasoning with answers for competitive exams

Problem #1

This reasoning problem consists of three figures and every figure have five number associated to it . Four numbers are at the corner of each figure and one number is at the centre of the figure. Look at last figure ,it have ? in its centre . So the solution of this problem is to find the value of question mark using four numbers associated to it . 

          But the biggest problem is how to utilised these four numbers to get the value of this question mark?

          Now watch carefully the 1st two figures . since these figures have some values of middle numbers. 

          Now we have to find or search the  formula for these four numbers in each figure to utilised them in any possible way to get middle or central number. 

         The same formula will be applicable to third figure to find out the value of question mark.

Formula :- The middle Number in each figure is one tenth of product of remaining numbers. 

Solution:-

 ( 4 × 5 × 7 × 6 ) ÷ 10 = 840 ÷ 10 = 84 ( Middle number in 1st figure).

 (2 × 8 × 4 × 5 ) ÷ 10 = 320 ÷ 10 = 32 ( Middle number in 2nd figure).

(5 × 6 × 9 × 2 )÷ 10 = 540 ÷ 10 = 54 ( Middle number in 3rd figure).

 Option (1) 54 is correct option 

Problem #2

This reasoning problem also consists of three figures and every figure have five number associated to it . Four numbers are at the corner of each figure and one number is at the centre of the figure. Look at last figure ,it have ? in its centre . So the solution of this problem is to find the value of question mark using four numbers associated to it. 

          But the main problem is how to use these four numbers to get the value of this question mark?

          Now watch carefully the 1st two figures . since these figures have some values of middle numbers. 

          Now we have to find or search the  formula for these four numbers in each figure to utilised them in any possible way to get middle or central number. 

         The same formula will be applicable to third figure to find out the value of question mark.

Formula:-:- The middle Number in each figure is two less than the sum of remaining numbers. 

Solution:-

(4 + 5 + 7 + 6 ) - 2 = 22 - 2 = 20 ( Middle number in 1st figure).

(2 + 8 + 4 + 7 ) - 2 = 21 - 2 = 19 ( Middle number in 2nd figure).

(5 + 6 + 9 + 8 ) - 2 = 28 - 2 = 26 ( Middle number in 3rd figure),

Option (4) 26 is correct option.

Problem #3

This reasoning problem also have three figures and every figure have five number attached to it . Four numbers are at the corner of each figure and one number is at the middle of the same figure.             Since last figure have question mark in its centre . So the solution of this problem is to find the value of question mark using four numbers associated to it . 

          But the biggest problem is how to utilised these four numbers to get the value of this question mark?

          Now watch carefully the 1st two figures . since these figures have some values of middle numbers. 

          Now we have to find or search the  formula for these four numbers in each figure to utilised them in any possible way to get middle or central number. 

         The same formula will be applicable to third figure to find out the value of question mark.

Formula:- [{Left number × Top most number } + Right number ] - bottom number.

Solution:- 

 {(4 × 5) + 7 }- 20 = ( 20 + 7 ) - 20 = 27 - 20 = 7 ( Middle number in 1st figure) . 

 {(2 × 8 ) + 4} - 12 = ( 16 + 4 ) - 12 = 20 - 12 = 8 ( Middle number in 2nd figure). 

{(4 × 12 ) + 12} - 51 = ( 48 + 12 ) - 51 = 60 - 51 = 9 ( Middle number in 3rd figure). 

Option (2)9 is correct option.

Problem #4

This reasoning problem also have three figures and every figure have five number attached to it . Four numbers are at the corner of each figure and one number is at the middle of the same figure.

           Since 2nd figure have question mark in its centre . So the solution of this problem is to find the value of question mark using four numbers associated to it . 

          But the biggest problem is how to utilised these four numbers to get the value of this question mark?

          Now watch carefully the 1st and 3rd figures . since these figures have some values of middle numbers. 

          Now we have to find or search the  formula for these four numbers in each figure to utilised them in any possible way to get middle or central number. 

         The same formula will be applicable to 2nd figure to find out the value of question mark.

Formula:-[{Left number × Top most number } + Right number ] - bottom number.

Solution:-

{(4 × 5 ) + 7 } - 16 = ( 20 + 7 ) - 16 = 27 - 16 = 11 ( Middle number in 1st figure). 

 {(4 × 12 ) + 1} - 33 = ( 48 + 1 ) - 33 = 49 - 33 = 16 ( Middle number in 3rd figure) .

{(2 × 8 ) + 3} - 12 = ( 16 + 3 ) - 12 = 19 - 12 = 7 ( Middle number in 2nd figure) . The value of question mark.  

Option (4)7 is correct option.
