Numerical Reasoning Sums To Improve Your Skills

Introduction

Numerical reasoning refers to the ability to understand and analyze numerical information, solve mathematical problems, and make decisions based on quantitative data. It involves the application of mathematical concepts and principles to real-world scenarios, and the ability to interpret and draw conclusions from numerical data. These types of puzzles are more commonly used in competitive exams, interview assessments, and so on. Practice these numerical reasoning puzzles with answers and put a basement to your career foundation with the help of Nithra Jobs.

1. Identify the missing number in diagram?

A.5
B.9
C.6
D.4
Ans: 5
Explanation:
The values in the segments of the middle circle equal the difference between the values in corresponding segments of the left- and right-hand circles.
Ex: (i) 4 - 2 = 2, 10 - 3 = 7, 6 - 4 = 2
(ii) 4 - 1 = 3, 2 - 1 = 1, 12 - 7 = 5

2. Can you find the missing number?

A.193
B.191
C.196
D.199
Ans: 196
Explanation:
Starting with the top left segment, and moving clockwise around the circle, numbers follow the sequence of square numbers, from 121 to 256.
Ex: 11 * 11 = 121, 12 * 12 = 144, 13 * 13 = 169
14 * 14 = 196, 15 * 15 = 225, 16 * 16 = 256.

3. Can you find the missing number in box?

A.15
B.17
C.11
D.18
Ans: 11
Explanation:
In each diagram the central value equals the difference between the sums of the number in the left-hand column and the sums of the number in the right-hand column.
Ex: (i) 4 + 2 + 6 = 12, 1 + 3 + 2 = 6 ⇒ 12 - 6 = 6
(ii) 3 + 1 + 4 = 8, 9 + 8 + 2 = 19 ⇒ 19 - 8 = 11
(iii) 4 + 6 + 7 = 17, 2 + 1 + 3 = 6 ⇒ 17 - 6 = 11

4. Find the number that replaces the question mark in diagram.

A.1
B.4
C.2
D.3
Ans: 3
Explanation:
Work through the diagram in columns. The value in the center of each column equals the difference between the sum of the top 2 numbers and the bottom two numbers.
Ex: (i) 3 + 1 = 4, 6 + 2 = 8 ⇒ 8 - 4 = 4
(ii) 7 + 2 = 9, 5 + 1 = 6 ⇒ 9 - 6 = 3
(iii) 4 + 5 = 9, 2 + 2 = 4 ⇒ 9 - 4 = 5
(iv) 2 + 8 = 10, 7 + 6 = 13 ⇒ 13 - 10 = 3
(v) 3 + 9 = 12, 3 + 1 = 4 ⇒ 12 - 4 = 8

5. Find the number that replaces the question mark in circle.

A.8
B.4
C.6
D.5
Ans: 6
Explanation:
Working through the diagram in rows, and reading each row as a whole number, the diagram represents a subtraction sum.
Ex: 203 - 7 = 196

6. Find the number that replaces the question mark.

A.6
B.9
C.14
D.10
Ans: 6
Explanation:
Numbers in boxes from the second row up equal the average of the 2 numbers in the boxes directly below. Continue to the apex of the triangle.
Ex: (i) 9 + 7 = 16 / 2 = 8, 7 + 5 = 12 / 2 = 6, 5 + 3 = 8 / 2 = 4
(ii) 8 + 6 = 14 / 2 = 7, 6 + 4 = 10 / 2 = 5
(iii) 7 + 5 = 12 / 2 = 6

7. Find the number that replaces the question mark in the circle.

A.257
B.259
C.253
D.252
E.253
Ans: 253
Explanation:
Starting at the top left, and moving through the diagram in a z shape, double each number and add 3 to give the next number along.
Ex: 1 + 1 = 2 + 3 = 5, 5 + 5 = 10 + 3 = 13, 13 + 13 = 26 + 3 = 29,
29 + 29 = 58 + 3 = 61, 61 + 61 = 122 + 3 = 125, 125 + 125 = 250 + 3 = 253

8. Find the number that replaces the question mark in diagram.

A.6
B.8
C.9
D.12
Ans: 8
Explanation:
Working in rows, from left to right, double the left-hand number to get the middle number and add two to this to get the right-hand number.
Ex: (i) 5 + 5 = 10 ⇒ 10 + 2 = 12
(ii) 4 + 4 = 8 ⇒ 8 + 2 = 10
(iii) 3 + 3 = 6 ⇒ 6 + 2 = 8

9. Find the number that replaces the question mark.

A.22
B.19
C.16
D.14
Ans: 22
Explanation:
Add the number at each corner of the diagram to its 2 adjacent numbers. The total is always 30.
Ex: 10 + 18 + 2 = 30, 18 + 5 + 7 = 30,
17 + 7 + 6 = 30, 2 + 22 + 6 = 30

10. Find the number that replaces the question mark.

A.3
B.4
C.5
D.9
Ans: 9
Explanation:
Working clockwise around the 3 triangles, the sum of the outer digits in each triangle is written in the center of the triangle one place clockwise.
Ex : 2 + 3 + 7 = 12, 8 + 1 = 9, 5 + 4 + 2 = 11
