Ten Important Reasoning questions with answers for competitive exams


Problem #1 



Reasoning questions with answers

This reasoning problem is a box problem of 4 rows and 3 columns, where the the value of question mark in last row we have to find. 

Formula :- 

Sum of the squares of 1st two columns = Squares of 3rd  column

1st Row

3² + 4² = 5²
➡ 9 + 16 = 25
➡ 25 = 25
L H S = R H S

2nd Row

6² + 8² = 10²
➡ 36 + 64 = 100
➡ 100 = 100
L H S = R H S

3rd Row

7² + 24² = 25²
➡ 49 + 576 = 625
➡ 625 = 625
L H S = R H S

4th Row

12² + ?² = 13²
➡ 144 + ?²  = 169
➡ ?²  = 169 -144
➡ ?²  = 25 , Taking square root on both sides
? = 5

Option (C)5 is correct option

Problem #2


Reasoning questions with answers

Formula :- 

Five less than the product of sum of two corner's numbers in each rectangle. 

1st Rectangle

{(11 + 4) × ( 9 + 5 ) } - 5  = (15 × 14) - 5 = 210 - 5 = 205

2nd Rectangle

{(21 + 1) × ( 3 + 2 ) } - 5 = (22 × 5) - 5 = 110 - 5 = 105

3rd Rectangle

{(62 + 5) × ( 1 + 1 ) } - 5  = ( 67 × 2) - 5 = 134 - 5 = 129 = ? 
Option (2)129 is correct option

Problem #3

Reasoning questions with answers
This reasoning problem consists of three triangles and every triangle have four numbers ,three around the triangle and one in the centre of the triangle. 

Formula :-  

Product of all the outer numbers  = Middle numbers

1st Figure

5 × 6 × 4 = 120 ⇒1 + 2 + 0 = 3 ( Middle number in 1st triangle ) 

2nd Figure

6 × 7 × 5 = 210  ⇒2 + 1 + 0 = 3 ( Middle number in 2nd triangle ) 

3rd Figure

4 × 8 × 10 = 320 ⇒3 + 2 + 0 = 5 ( Middle number in 3rd triangle ) 
Option (2)5 is correct option.


Problem #4


Reasoning questions with answers

This reasoning problem consists of three squares and every squares have four small squares , And each small square contains a number in it. If we add all the numbers in each small square then we shall have total of 35 in each small square. 

Formula :- Sum of all the numbers in a square = 35

1st Square

5  + 12 + 8 + 10 = 35  

2nd Square

8 + 16 + 6 + 5 = 35

3rd  Square

4 + 10 + ? + 15 = 35
29 + ? = 35
? = 35 - 6
? = 6

Option (4)6 is correct option

Problem #5


Reasoning questions with answers

1st Quadrant:-

HCF ( Highest common Factor ) of 4 and 8 is 4

2nd Quadrant:-

HCF ( Highest common Factor ) of 3 and 5 is 1

3rd Quadrant:-

HCF ( Highest common Factor ) of  6 and 12 is 6

4th Quadrant:-

HCF ( Highest common Factor ) of 10 and 25 is 5
Option (2)5 is correct option

Problem #6


Reasoning questions with answers
All the numbers which are around the circle in any figure do not have any role to make the number in centre of the circle. But all the digits of the central number in 1st figure are reversed, So in same way all the digits of the central number in 2nd figure will be reversed to get the central/middle number in the 3rd figure. Hence 6543 will be the value of question mark. 
Option (4)6543 is correct option .


Problem #7


Reasoning questions with answers
Sum of  all the numbers in any particular column are same for all column like

Formula :- 

All Numbers in any columns have equal total

[10 + 7](1st Column) = 17 = [9 + ? + 6](2nd Column)  = [ 15 +2] = 17( 3rd Column) . Now calculating the value of ? from any two column. 
→ ? = 2
Option (1)2 is correct option

 Problem #8


Reasoning questions with answers

Sum of squares of three numbers in upper line is equal to the number in lower line in each figure.

Formula :-  


Sum of the squares of numbers in 1st row  = Number in 2nd row 

1st Figure :-

2² + 5² + 6² = 4 + 25 + 36 = 65

2nd Figure :-

6² + 8² + 9² = 36 + 64 + 81 = 81

3rd Figure :-

2² + 8² + 7² = 4 + 64 + 49 = 117
Option (2)117 is correct option

Problem #9


Reasoning questions with answers

In these types of reasoning questions either we can check the sum or product of all the numbers in any rows or column. If the sum or product of all the rows or columns is found to be same except the row or column in which question mark lies , then we can choose the value of question mark out of four given options to get the answer.
Sum of all the numbers in every row is 20.
2 + 3 + 7 + 8 = 20 ( Last Row ) 
4 + 7 + 9 = 20  ( 2nd Last Row ) 
11 + 9 = 20  ( 2nd Row ) 
 Hence the value of  "?"  must be 20
Option (4)20 is correct option


Problem #10


Reasoning questions with answers

This Reasoning question have three triangles in it. And every triangle consists of four numbers around it , The middle number in each triangle can be written using the formula given below 

Formula :- b² - ( 1st side² - 2nd side²) = Middle number

1st Triangle :-

7² - ( 4² + 3²) = 49 - (16 + 9 ) = 49 -25 =  24  42

2nd Triangle :-

8² - ( 6² + 3²) = 64 - (36 + 9 ) = 64 - 45 =  19  91

3rd Triangle :-

9² - ( 5² + 3²) = 81 - (25 + 9 ) = 81 - 34 =  47 74
Option (3)74 is correct option

Conclusion

  3. The reasoning is a very important part of Maths, especially when you are preparing for competitive exams. The calculative part of the reasoning is a little tricky so you need to do a lot of practice to understand the tricks and methods of solving the questions. Once you have proper knowledge and guidance. It becomes easy to solve the tough question of reasoning. Proper guidance is required to understand the concepts and achieve the desired results. There are many tutors and institutions outside providing maths tuition at high cost and less experience in the field. If you are looking for the best maths tuition then, smile tutor is one of the best to provide maths tuition with a skilled and experienced teachers.
