Numerical Reasoning Puzzles to Keep You Sharp

Introduction

Numerical reasoning puzzles are problems or puzzles that require the use of numerical reasoning skills to solve. These puzzles come in many forms, including number sequences, mathematical equations, and logic puzzles. They are a fun and challenging way to exercise the brain and improve numerical reasoning skills. Solving numerical reasoning problems can also help develop problem-solving skills, logical thinking, and attention to detail. These skills are required for job interviews. By developing your skills, you can apply for the job offers in Tamil Nadu at Nithra Jobs for free. It has several job openings in Tamil Nadu from various fields.

1. What number should replace the question mark with answer?


A.70
B.72
C.65
D.60
Ans: 65
Explanation:
Start the top and work down, add the separate digits of the top number to the number itself to give the next one down. Then subtract 12 to give the one after this continue with this alternating pattern.
Ex: 61 separate 6 + 1 = 7 ⇒ 61 + 7 = 68, 68 - 12 = 56, 56 separate 5 + 6 = 11 ⇒ 56 + 11 = 67, 67 - 12 = 55, 55 separate 5 + 5 = 10 ⇒ 55 + 10 = 65

2. What number should replace the question mark with answer?


A.14
B.15
C.18
D.20
Ans: 15
Explanation:
Working from the bottom row to the apex of the triangle, the sum of the values in each row follows this sequence 18, 17, 16, 15.
Ex: 8 + 4 + 5 + 1 = 18, 9 + 7 + 1 = 17, 14 + 2 = 16, 15.

3. What number should replace the question mark with answer?


A.6
B.4
C.1
D.8
Ans: 6
Explanation:
Each row and column of the diagram adds up to 15.
Ex: Rows ⇒ 7 + 2 + 6 = 15, 3 + 9 + 3 = 15, 5 + 4 + 6 = 15
Columns ⇒ 7 + 3 + 5 = 15, 2 + 9 + 4 = 15, 6 + 3 + 6 = 15

4. Identify the figure from the question?


A.9
B.17
C.13
D.3
Ans: 3
Explanation:
Working in rows, the number in the central oval equals the sum of the left- and right-hand numbers, divided by 3.
Ex: 5 + 7 = 12 / 3 = 4, 12 + 6 = 18 / 3 = 6, 7 + 2 = 9 / 3 = 3

5. Identify the figure from the question?


A.522
B.518
C.513
D.521
Ans: 518
Explanation:
As you move clockwise, subtract 3 from the first number and multiply by 2 to give the next one round.
Ex: 7 - 3 = 4 * 2 = 8, 8 - 3 = 5 * 2 = 10, 10 - 3 = 7 * 2 = 14, 14 - 3 = 11 * 2 = 22, 22 - 3 = 19 * 2 = 38,
38 - 3 = 35 * 2 = 70, 70 - 3 = 67 * 2 = 134, 134 - 3 = 131 * 2 = 262, 262 - 3 = 259 * 2 = 518

6. Identify the figure from the question?


A.1211
B.1213
C.1217
D.1220
Ans: 1213
Explanation:
Start with 1 and move clock wise multiply the previous number by 3 and add 4 to give the next number around.
Ex :(i) 3 * 3 = 9 + 4 = 13
(ii) 13 * 3 = 39 + 4 = 43
(iii) 43 * 3 = 129 + 4 = 133
(iv) 133 * 3 = 399 + 4 = 403
(v) 403 * 3 = 1209 + 4 = 1213

7. Identify the figure from the question?


A.105
B.100
C.95
D.90
Ans: 100
Explanation:
Starting with the top left segment, and moving clockwise around the circle, numbers follow the sequence of square numbers, from 25 to 100.
Ex: 5 * 5 = 25, 6 * 6 = 36, 7 * 7 = 49,
8 * 8 = 64, 9 * 9 = 81, 10 * 10 = 100

8. Identify the figure from the question?


A.7
B.8
C.2
D.3
Ans: 3
Explanation:
Add the number at each corner of the diagram to its 2 adjacent numbers. The total is always 15.
Ex: 5 + 1 + 9 = 15, 1 + 7 + 7 = 15,
9 + 1 + 5 = 15, 3 + 7 + 5 = 15

9. Identify the figure from the question?


A.2
B.1
C.6
D.4
Ans: 2
Explanation:
In each diagram, the central value equals the multiplication of the left- and right-hand digits, minus the multiplication of the upper and lower digits.
Ex: (i) 4 * 3 = 12, 2 * 1 = 2 ⇒ 12 - 2 = 10
(ii) 6 * 7 = 42, 4 * 5 = 20 ⇒ 42 - 20 = 22
(iii) 8 * 7 = 56, 4 * 2 = 8 ⇒ 56 - 8 = 48

10. Identify the figure from the question?


A.2811
B.2810
C.2819
D.2815
Ans: 2810
Explanation:
As you move clockwise, add 3 from the first number and multiply by 2 to give the next one round.
Ex: 5 + 3 = 8 * 2 = 16, 16 + 3 = 19 * 2 = 38, 38 + 3 = 41 * 2 = 82, 82 + 3 = 85 * 2 = 170,
170 + 3 = 173 * 2 = 346, 346 + 3 = 349 * 2 = 698, 698 + 3 = 701 * 2 = 1402, 1402 + 3 = 1405 * 2 = 2810

Conclusion

In conclusion, number reasoning problems are a great way to improve numerical reasoning skills and overall cognitive function. They are not only challenging and fun, but they also help develop critical thinking and problem-solving abilities. Whether you're looking to improve your skills for work or simply want to exercise your brain, numerical reasoning puzzles are a great way to do so.
