1. Find the missing number in question.

A.12
B.17
C.19
D.21
Ans: 12
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) 3 + 1 = 4
(ii) 3 + 5 = 8
(iii) 5 + 5 = 10
(iv) 7 + 5 = 12

2. Find the missing number in question.

A.39
B.31
C.40
D.35
Ans: 31
Explanation:
As you move to the right, double the number and subtract 4, then 3, then 2, then 1 to give the next number along.
Ex: (i) 5 + 5 = 10, 10 - 4 = 6
(ii) 6 + 6 = 12, 12 - 3 = 9
(iii) 9 + 9 = 18, 18 - 2 = 16
(iv) 16 + 16 = 31, 32 - 1 = 31

3. Find the missing number in question.

A.10
B.8
C.3
D.13
Ans: 3
Explanation:
Split the diagram into 3 vertical columns. The sum of the numbers in each column equal 50.
Ex: 25 + 25 = 50, 30 + 20 = 50, 40 + 3 + 7 = 50

4. Find the missing number in question.

A.11
B.7
C.6
D.9
Ans: 7
Explanation:
Start any where on the diagram and move clockwise calculating the sum of every third circle . This always equals 15.
Ex: 5 + 5 + 5 = 15, 1 + 7 + 7 = 15, 2 + 7 + 6 = 15

5. Find the missing number in question.

A.25
B.27
C.29
D.21
Ans: 25
Explanation:
In each row, add the left and central numbers together, double it and add 1 to get the right-hand value.
Ex: (i) 6 + 7 = 13, 13 + 13 = 26 + 1 ⇒ 27
(ii) 4 + 6 = 10, 10 + 10 = 20 + 1 ⇒ 24
(iii) 3 + 9 = 12, 12 + 12 = 24 + 1 ⇒ 25

6. Find the missing number in question.

A.8
B.6
C.12
D.4
Ans: 6
Explanation:
In each diagram, the central value equals the difference between the multiplication of the number in the left-hand column and the multiplication of the number in the right-hand column.
Ex: (i) 4 × 1 × 5 = 20, 3 × 7 × 2 = 42 ⇒ 42 - 20 = 22
(ii) 3 × 5 × 2 = 30, 6 × 4 × 1 = 24 ⇒ 30 - 24 = 6

7. Find the missing number in question.

A.3
B.10
C.13
D.5
Ans: 3
Explanation:
Using the lower two circles as a source, the values in corresponding segments of the top circle equal the sums of the numbers in the lower two circles
Ex: (i) 2 + 6 = 8, 4 + 3 = 7
(ii) 1 + 9 = 10, 7 + 3 = 10

8. What number should replace the question mark?

A.14
B.16
C.18
D.12
Ans: 12
Explanation:
In each column of the diagram the central value equals the average of the upper and lower numbers.
Ex: 8 + 4 = 12 ⇒ 12/2 = 6
(ii) 2 + 2 = 4 ⇒ 4/2 = 2
(iii) 10 + 12 = 22 ⇒ 22/2 = 11

9. What number should replace the question mark?

A.21
B.25
C.14
D.17
Ans: 14
Explanation:
In each star, the central value equals the sum of the top and lower two numbers. Minus the left- and right-hand numbers.
Ex: (i) 4 + 3 + 2 = 9, 1 + 2 = 3 ⇒ 9 - 3 = 6
(ii) 5 + 6 + 8 = 19, 4 + 3 = 7 ⇒ 19 - 7 = 12
(iii) 12 + 12 + 3 = 27, 6 + 7 = 13 ⇒ 27 - 13 = 14

10. What number should replace the question mark?

A.0
B.7
C.5
D.1
Ans: 0
Explanation:
Read each row of 3 numbers as a digit number and add the top row value to the middle row, to give the result written in the bottom row.
Ex: 239 + 468 = 707
