Ten Important Box Reasoning questions with answers for competitive exams

Problem #1 

This reasoning problem consists of three figures and every figure have three numbers associated to it . So the solution of this problem is to find the value of question mark using other two numbers associated to it . 

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

          Now watch carefully the 1st two figures . since these figures have some values at bottom lines. 

          Now we have to find or search the  formula for these two numbers in each figure to utilised them in any possible way to get   number in bottom line. 

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

Formula :- 

The difference of  squares of  greater number to smaller number in upper line in every figure is equal to number in lower line in every figure.

4³  - 6² = 64 - 36 = 28 (1st figure)

3³ - 2² = 27 - 4 = 23 ( 2nd figure)

5³  - 5² = 125 - 25 = 100 (3rd figure), This number will be the value of question mark.

Option (3)100  is correct option

Problem #2

This reasoning problem also consists of three figures and every figure have three numbers associated to it . So the solution of this problem is to find the value of question mark using other two numbers associated to it . 

But the main purpose is how to utilised other two numbers to get the value of this question mark?

          Now watch carefully the 1st two figures . since these figures have some values at bottom lines. 

          Now we have to find or search the  formula for these two numbers in each figure to utilised them in any possible way to get   number in bottom line. 

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

Formula :- 

The sum of cubes of  1st number and  squares  of  2nd number in upper line in every figure is equal to number in lower row in every figure.

4³ + 6² = 64 + 36 = 100 (1st figure)

2³ + 7² = 8 + 49 = 57 (2nd figure)

4³ + 4² = 64 + 16 = 80 (3rd figure)

Option (4)80  is correct option

Problem #3 

This reasoning problem is a box problem of 3 rows and 3 columns, where the the value of question mark in last row we have to find. 

Formula :- 

Four times the difference of the 1st columns and 2nd column = Number in 3rd  column.

C3 = 4  ×  (C1 - C2)

4 × ( 9 - 4 ) = 4 × 5 = 20 ( Number in 1st row 3rd column ) . 

 

4 × ( 8 - 5 ) = 4 × 4 = 16 ( Number in 2nd row 3rd column )

This box problem also consist of three rows and three columns. And we have to find the value of question mark after analysing the pattern of all the numbers in this box.

    Since question mark is in the 3rd column of 3rd row, so we can use any two number in any two particular rows to find the value of 3rd  number in that particular row.

Row wise

Formula:-  2 × (1st number - 2nd number ) = 3rd number 

( 14  - 10 ) × 2 = 4 × 2 = 8 ( Number in 3rd row 1st column) 

( 16  - 15 ) × 2 = 1 × 2 = 2 ( Number in 3rd row 1st column) 

( 19  - 13 ) × 2 = 6 × 2 =  ? = 12 ( Number in 3rd row 1st column) 

Option (D)12 is correct option.

Problem # 9

Exam Cracker

This box problem consist of three rows and three columns. And we have to find the value of question mark after studying the pattern of all the numbers in this box.

    Since question mark is in the 1st column of 3rd row, so we can use any two number in any two particular columns to find the value of 3rd  number in that particular column.

Column Wise

Formula:-  cube of 1st number  +  ( cube root of 2nd number ) = 3rd number 

(2)³   +  ∛8  = 8 +  2 = 10

(3)³   +  ∛64 = 27 +  4 = 31

(1)³   +  ∛27 = 1 + 3 =  4

Option (A)4 is correct option.

This box problem also consist of three rows and three columns. And we have to find the value of question mark after analysing the pattern of all the numbers in this box.

    Since question mark is in the 2nd column of 3rd row, so we can use any two number in any two particular columns to find the value of 3rd  number in that particular column.

Row wise

Formula:-   (3rd number - 1st number ) = Middle number 

( 3/2 ) - ( 1 ) = 1/2  (Middle number in 1st row ) 

( 8/3 ) - ( 2 ) = 2/3  (Middle number in 2nd row )

( 19/5 ) - ( 3 ) = 4/5  (Middle number in 3rd row )

Option (D)4/5 is correct option.
