Numerical reasoning to improve your problem solving skills

Introduction

Numerical reasoning assessments are often used by employers as part of the hiring process to evaluate a candidate's ability to work with numbers and data. These assessments typically involve multiple-choice questions and require the candidate to use mathematical concepts such as percentages, ratios, and averages to solve problems. Nithra Jobs offers an assessment test to evaluate a candidate's numerical reasoning skills. This assessment helps individuals understand their strengths and weaknesses in working with numbers, which can be an important factor to get success in your career.

1. Which number replaces the question mark?

A.7
B.8
C.21
D.37
Ans: 7
Explanation:
Starting at the top left and moving down then to the right and up in a snake and ladder pattern, add the first two numbers together and subtract 1 to get the next in the sequence.
Ex: 9 + 5 = 14, 14 - 1 = 13
4 + 12 = 16, 16 - 1 = 15
7 + 4 = 11, 11 - 1 = 10
10 + 2 = 12, 12 - 1 = 11
5 + 3 = 8, 8 - 1 = 7

2. Which number replaces the question mark?

A.25
B.18
C.16
D.15
Ans: 16
Explanation:
Moving from top to bottom numbers increase by 1 then 2, before repeating this pattern and each number add by 1 to get the result.
Ex: 4 + 1 = 5, 5 + 1 = 6
6 + 2 = 8, 8 + 1 = 9
9 + 1 = 10, 10 + 1 = 11
11 + 2 = 13, 13 + 1 = 14
14 + 1 = 15, 15 + 1 = 16

3. Which number replaces the question mark?

A.16
B.19
C.8
D.4
Ans: 4
Explanation:
Working in rows starting with the center row, add the left- and right-hand digits together and add 2 put the result in the central space. Repeat for the upper and lower rows, but put the result in the opposite sides.
Ex: 3 + 9 = 12, 12 + 2 = 14
2 + 4 = 6, 6 + 2 = 8
5 + 7 = 12, 12 + 2 = 14

---

4. Which number replaces the question mark?

A.13
B.15
C.16
D.21
Ans: 16
Explanation:
Starting with the top segment and moving clockwise, add the numbers in the first two segments together and subtract 5 to give the next number around.
Ex: 12 + 1 = 13, 13 - 5 = 8
1 + 8 = 9, 9 - 5 = 4
8 + 4 = 12, 12 - 5 = 7
4 + 7 = 11, 11 - 5 = 6
7 + 6 = 13, 13 - 5 = 8
6 + 8 = 14, 14 - 5 = 9
8 + 9 = 17, 17 - 5 = 12
9 + 12 = 21, 21 - 5 = 16

---

5. Which number replaces the question mark?

A.40
B.20
C.9
D.1
Ans: 20
Explanation:
Starting with the numbers in the top row, left to right multiply each one by 4 and write the results in the lower row, from right to left.
Ex: 5 * 4 = 20 (right side) 3 * 4 = 12 (left side) 7 * 4 = 28 (center column)

---

6. Can you find the missing number?

A.5
B.6
C.7
D.10
Ans: 6
Explanation:
Starting from top to bottom, reading each pair of numbers as a 2-digit value, the numbers follow the sequence of square numbers, from 16 to 64, each written back to front.
Ex: (4)² = 61 (16 write in back to front)
(5)²= 25 (52 write in back to front)
(6)² = 36 (63 write in back to front)
(7)² = 49 (94 write in back to front)
(8)² = 64 (46 write in back to front)

7. Can you find the missing number?

A.12
B.15
C.16
D.21
Ans: 16
Explanation:
In each triangle, the center value equals the product of the 3 corner numbers by subtracting the sum of the 3 outer numbers.
Ex: ( 6 * 3 * 2 ) - ( 6 + 3 + 2 ) = 36 - 11 = 25
( 9 * 3 * 5 ) - ( 9 + 3 + 5 ) = 135 - 17 = 118
( 1 * 4 * 7 ) - ( 1 + 4 + 7 ) = 28 - 12 = 16

---

8. Can you find the missing number?

A.14
B.12
C.10
D.9
Ans: 9
Explanation:
Reading each pair of numbers as a 2-digit numbers, they follow the sequence of square numbers from 6 to 10 and each number subtracted by 1.
Ex: 6 * 6 = 36, 36 - 1 = 35, 7 * 7 = 49, 49 - 1 = 48, 8 * 8 = 64, 64 - 1 = 63, 9 * 9 = 81, 81 - 1 = 80, 10 * 10 = 100, 100 - 1 = 99

---

9. Can you find the missing number?

A.135
B.282
C.381
D.542
Ans: 381
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: 3 + 3 = 6, 6 + 3 = 9, 9 + 9 = 18, 18 + 3 = 21, 21 + 21 = 42, 42 + 5 = 45, 45 + 45 = 90, 90 + 3 = 93, 93 + 93 = 186, 186 + 3 = 189, 189 + 189 = 378, 378 + 3 = 381

---

10. Can you find the missing number?

A.28
B.34
C.36
D.48
Ans: 34
Explanation:
Moving to the right, double each number and subtract 2 to give the next number along.
Ex: 3 + 3 = 6, 6 - 2 = 4, 4 + 4 = 8, 8 - 2 = 6, 6 + 6 = 12, 12 - 2 = 10, 10 + 10 = 20, 20 - 2 = 18, 18 + 18 = 36, 36 - 2 = 34
