Maths Puzzles Questions and Answers
We have provided a comprehensive set of Maths Puzzles Questions and Answers designed to enhance problem-solving skills and logical thinking. These puzzles cover a wide range of mathematical topics, including arithmetic, algebra, geometry, and number theory.
1. Find the missing number.
Solution:
In the given puzzle, 5 × 8 = 40 5 × 6 = 30 8 × 3 = 24 6 × 3 = 18 Therefore, the missing number is 18.
2. Identify the number to be written in the empty place.
Solution:
In the given puzzles, the sum of three numbers (both in columns and rows) is 15. 8 + 3 + 4 = 15 6 + 7 + 2 = 15 8 + 1 + 6 = 15 3 + 5 + 7 = 15 Let x be the missing number. 4 + x + 2 = 15 6 + x = 15 x = 15 – 6 = 9 Hence, the required number is 9.
3. Observe the following and find the missing value.
Solution:
The given maths puzzle has the following pattern. 5 × 8 = 40 8 2 = 8 × 8 = 64 7 × 9 = 63 9 2 = 9 × 9 = 81 4 × 4 = 16 4 2 = 4 × 4 = 16 Therefore, the missing number is 16.
4. What is the missing number in the following puzzle?
Solution:
In the given puzzles, the sum of two numbers in the opposite portions is the same. 11 + 13 = 24 7 + 17 = 24 8 + 16 = 24 4 + ? = 24 ? = 24 – 4 = 20 Thus, the missing number is equal to 20.
5. Complete the following puzzle.
Solution:
Let p and q be the two numbers in the first row. Let r and s be the two numbers in the second row. p + q = 8….(1) r – s = 6….(2) p + r = 13….(3) q + s = 8….(4) Subtracting (3) from (1), we get; p + q – (p + r) = 8 – 13 q – r = -5….(5) Subtracting (4) from (1), we get; p + q – (q + s) = 8 – 8 p – s = 0 i.e., p = s Adding (2) and (4), we get; r – s + q + s = 6 + 8 r + q = 14….(6) Adding (5) and (6), we have; q – r + r + q = -5 + 14 2q = 9 q = 9/2 = 4.5 Substituting q = 4.5 in (1), p + 4.5 = 8 p = 8 – 4.5 = 3.5 So, s = 3.5 Substituting q = 4.5 in (6), r + 4.5 = 14 r = 14 – 4.5 = 9.5 Hence, the complete puzzle is given as:
6. What can be added in place of a question mark?
Solution:
Let us consider the lower part of the given puzzle.
| 4 = 2 2 |
49 = 7 2 |
| 14 = 2 × 7 |
A similar pattern exists in the remaining parts too. Now, consider the right part. 49 = 7 2 35/7 = 5 5 2 = 25 That means 7 × 5 = 35. Thus, the missing number is 25.

7. Find the number that can be replaced with (?) in the following puzzle.
Solution:
In the given puzzle,
| 4 |
6 |
| 24 = 4 × 6 |
576 = 24 × 24 |
And
| 3 |
5 |
| 15 = 3 × 5 |
15 × 15 = 225 |
Hence, 225 can be written in the missing place.
8. What will replace the (?) in the following puzzle?
Solution:
In the given puzzle, 6 × 7 = 42 3 × 7 = 21 ? × 7 = 63 ? = 63/7 = 9 Therefore, 9 should be written in place of a question mark.
9. Using four 9s and one 1, form any numerical expression such that it results in 100.
Solution:
Number of 9s = 4 i.e., 9, 9, 9, 9 Number of 1s = 1 Required numerical expression = 199 – 99 = 100
10. Consider the following:
A + B = 15
B × C = 84
C ÷ 4 = 3
B + D = 18
Find the value of D.
Solution:
Given, A + B = 15 B × C = 84 C ÷ 4 = 3 B + D = 18 Consider C ÷ 4 = 3. C/4 = 3 C = 3 × 4 = 12 Now, B × C = 84 B × 12 = 84 B = 84/12 = 7 From the given, A + B = 15 A + 7 = 15 A = 15 – 7 = 8 Also, B + D = 18 7 + D = 18 D = 18 – 7 = 11
