1. Which number replaces the question mark?


A.1
B.5
C.8
D.3
Ans: 1
Explanation:
Each adjacent group of three numbers total 20.
Ex: 8 + 7 + 5 = 20, 11 + 2 + 7 = 20, 6 + 2 + 12 = 20, 3 + 12 + 5 = 20, 11 + 4 + 5 = 20, 6 + 4 + 10 = 20, 1 + 10 + 9 = 20, 6 + 9 + 5 = 20

2. Which number replaces the question mark?


A.947
B.941
C.945
D.948
Ans: 941
Explanation:
For first two digits in the center value of each row = add first two digits in the left and right of the element. Last digit of center value of each row = add last digit in the left and right element.
Ex: (i) 51 + 30 = 81, 2 + 4 = 6
(ii) 42 + 19 = 61, 0 + 8 = 8
(ii) 72 + 22 = 94, 1 + 0 = 1

3. Which number replaces the question mark?


A.10
B.8
C.7
D.2
Ans: 7
Explanation:
In each star, the value at the center equals the difference between the sum of the top 3 numbers and the sum of the bottom 3 numbers.
Ex: (i) 4 + 7 + 2 = 13, 6 + 3 + 5 = 14, 14 - 13 = 1
(ii) 9 + 6 + 1 = 16, 8 + 3 + 2 = 13, 16 - 13 = 3
(iii) 2 + 1 + 4 = 7, 5 + 6 + 3 = 14, 14 - 7 = 7.

4. Which number replaces the question mark?


A.2
B.0
C.6
D.8
Ans: 8
Explanation:
Looking at lines of numbers from the top.
Ex: 9 * 7 = 63, 63 * 7 = 441, 441 * 7 = 3087

5. Which number replaces the question mark?


A.9
B.11
C.12
D.17
Ans: 9
Explanation:
Each number in the segment at the bottom is the sum of the four numbers in the sections either side.
Ex: (i) 4 + 3 + 1 + 2 = 10
(ii) 1 + 2 + 6 + 7 = 16
(iii) 6 + 7 + 9 + 3 = 25
(iv) 9 + 3 + 8 + 6 = 26

6. Can you find the missing number?


A.3
B.8
C.5
D.4
Ans: 5
Explanation:
It is the sum of the two digits (4 + 1) in the quadrant opposite.
Ex: 5 + 3 = 8, 6 + 5 = 11, 4 + 1 = 5, 1 + 2 = 3, 2 + 7 = 9, 8 + 3 = 11

7. Can you find the missing number?


A.39217
B.39220
C.39225
D.39221
Ans: 39217
Explanation:
Start with 1 and move clock wise multiply the number by 7 and subtract 3 to get the next number.
Ex: 1 * 7 = 7 ⇒ 7 - 4 = 3, 3 * 7 = 21 ⇒ 21 - 4 = 17, 17 * 7 = 119 ⇒ 119 - 4 = 115, 115 * 7 = 805 ⇒ 805 - 4 = 801, 801 * 7 = 5607 ⇒ 5607 - 4 = 5603, 5603 * 7 = 39221 ⇒ 39221 - 4 = 39217,

8. Can you find the missing number?


A.11
B.17
C.16
D.19
Ans: 17
Explanation:
In each row, add the left and central numbers together, double it and add 1 to give the right-hand value.
Ex: (i) 7 + 2 = 9, 9 + 9 = 18, 18 + 1 = 19
(ii) 6 + 8 = 14, 14 + 14 = 28, 28 + 1 = 29
(iii) 5 + 3 = 8, 8 + 8 = 16, 16 + 1 = 17

9. Can you find the missing number?


A.6
B.1
C.0
D.4
Ans: 6
Explanation:
From top to bottom, reading each pair of numbers as a 2-digit value, the numbers follow the sequence of square numbers, from 25 to 64, each written back to front.
Ex: (i) 5 * 5 = 25 ⇒ 52
(ii) 6 * 6 = 36 ⇒ 63
(iii) 7 * 7 = 49 ⇒ 94
(iv) 8 * 8 = 64 ⇒ 46

10. What number should replace the question mark?


A.4
B.0
C.7
D.5
Ans: 0
Explanation:
Working through the diagram in rows, the right-hand value equals the sum of any odd numbers in the rest of the row.
Ex: (i) First row: 7 + 3 = 10
(ii) Second row: 1
(iii) Third row: 5 + 9 = 14
(iv) Fourth row : no odd number so 0

Conclusion

In conclusion, number reasoning puzzles serve as captivating exercises that sharpen our numerical intuition and problem-solving prowess. By exploring the intricate dance of digits and uncovering hidden numerical patterns, we not only expand our mental faculties but also find beauty in the ordered world of mathematics.
