1. Can you find the missing number?
A.1
B.0
C.6
D.3
Ans: 1 Explanation:
In each H shape, the central number is equal to the difference between the sum of the 3 left hand numbers and the sum of the 3 right hand numbers.
Ex: (i) 4 + 7 + 1 = 12, 5 + 6 + 2 = 13 ⇒ 13 - 12 = 1
(ii) 3 + 2 + 5 = 10, 10 + 2 + 4 = 16 ⇒ 16 - 10 = 6
(iii) 7 + 2 + 3 = 12, 4 + 6 + 1 = 11 ⇒ 12 - 11 = 1
2. Which number replaces the question mark?
A.6
B.7
C.9
D.8
Ans: 9 Explanation:
Reading each pair of numbers in a row as a 2-digit number, values increase by 6 each time.
Ex: 35 + 6 = 41, 41 + 6 = 47, 47 + 6 = 53, 53 + 6 = 59
3. Which number replaces the question mark?
A.19
B.18
C.12
D.14
Ans: 18 Explanation:
Starting on the top left, and moving clockwise around the diagram, add the first two values together to give the next value along. Repeat this sequence.
Ex: 3 + 4 = 7, 4 + 7 = 11, 11 + 7 = 18, 11 + 18 = 29, 29 + 47 = 76
4. Which number replaces the question mark?
A.1
B.4
C.6
D.7
Ans: 6 Explanation:
In each group of diagrams, the center number equals the average of the four surrounding numbers.
Ex: (i) 12 + 4 + 9 + 3 = 28/4 = 7
(ii) 13 + 5 + 12 + 6 = 36/4 = 9
(iii) 8 + 3 + 2 + 7 = 20/4 = 5
(iv) 21 + 5 + 16 + 6 = 48/4 = 12
5. Which number replaces the question mark?
A.17
B.7
C.11
D.11
Ans: 7 Explanation:
In each diagram, the sum of the upper left and upper middle numbers is written in the center box, and the sum of the upper right and upper middle numbers is written in the lower central box.
Ex: (i) 3 + 12 = 15, 12 + 6 = 18
(ii) 11 + 4 = 15, 4 + 8 = 12
(iii) 8 + 3 = 11, 4 + 3 = 7
6. Can you find the missing number?
A.4
B.9
C.8
D.2
Ans: 2 Explanation:
Working in rows, the sum of numbers in each row follows the sequence 5, 10, 15, 20, 15, 10, 5.
Ex: 5, 2 + 1 + 7 = 10, 5 + 1 + 3 + 4 + 2 = 15, 1 + 3 + 7 + 2 + 1 + 4 + 2 = 20, 7 + 2 + 3 + 1 + 2 = 15, 6 + 2 + 2 = 10, 5
7. Can you find the missing number?
A.1
B.0
C.12
D.13
Ans: 1 Explanation:
Split the grid in half vertically, to give two columns, 3 squares wide. Working from top to bottom, left then right, and reading each 3 square row as a whole 3 digit number, the columns follow the sequence of square numbers, from 10 to 21.
Ex: 10 × 10 = 100, 11 × 11 = 121, 12 × 12 = 144, 13 × 13 = 169, 14 × 14 = 196, 15 × 15 = 225, 16 × 16 = 256, 17 × 17 = 289, 18 × 18 = 324, 19 × 19 = 361, 20 × 20 = 400, 21 × 21 = 441
8. Can you find the missing number?
A.19
B.18
C.15
D.1
Ans: 1 Explanation:
Taking any series of 3 numbers in a straight line in the diagram, their total is always 19.
Ex: 2 + 11 + 6 = 19, 4 + 6 + 9 = 19, 1 + 14 + 4 = 19, 16 + 1 + 2 = 19
9. Can you find the missing number?
A.8
B.4
C.7
D.6
Ans: 8 Explanation:
Divide the circle, horizontally and vertically, to give 4 quarters. The sum of the numbers in the segments of each quarter equals 11.
Ex: 7 + 4 = 11, 10 + 1 = 11, 6 + 5 = 11, 8 + 3 = 11
10. What number should replace the question mark?
A.1
B.5
C.7
D.0
Ans: 0 Explanation:
If you add up all the digits in any diagonal you will find the sum to be 25.
Ex: 3 + 11 + 4 + 7 = 25, 10 + 1 + 9 + 5 = 25, 6 + 11 + 6 + 2 = 25, 8 + 5 + 12 + 0 = 25
