6 + 8 + 7 = 21, 21 / 3 = 7
9 + 11 + 7 = 27, 27 / 3 = 9

2. Can you find the missing number?

A.5
B.16
C.48
D.63
Ans:63
Explanation:
In each circle, add the lower 2 digits together and multiply by the upper digit to give the result in the upper semi-circle.
2 + 3 = 5, 5 * 6 = 30
1 + 4 = 5, 5 * 5 = 25
3 + 6 = 9, 9 * 7 = 63

3. Find the number that replaces the question mark.

A.10
B.7
C.4
D.2
Ans:4
Explanation:
In each circle, add together the numbers the left- and right-hand segments and subtract 3 to give the result in the lower segment.
6 + 3 = 9, 9 - 3 = 6
3 + 4 = 7, 7 - 3 = 4
5 + 2 = 7, 7 - 3 = 4

4. Find the number that replaces the question mark.

A.12
B.7
C.4
D.2
Ans:2
Explanation:
In each segment of the circle, multiply the outer 2 numbers together and subtract the sum of the outer 2 numbers in the opposite segment to give the value in the inner segment.
( 7 * 3 ) - ( 7 + 3 ) = 21 - 10 = 11
( 9 * 2 ) - ( 9 + 2 ) = 18 - 11 = 7
( 3 * 6 ) - ( 3 + 6 ) = 18 - 9 = 9
( 6 * 4 ) - ( 6 + 4 ) = 24 - 10 = 14
( 6 * 6 ) - ( 6 + 6 ) = 36 - 12 = 24
( 3 * 2 ) - ( 3 + 2 ) = 6 - 5 = 1
( 5 * 4 ) - ( 5 + 4 ) = 20 - 9 = 11
( 2 * 5 ) - ( 2 + 5 ) = 10 - 7 = 3

5. Find the number that replaces the question mark.

A.8
B.11
C.18
D.24
Ans:8
Explanation:
Working in rows, the sum of numbers in each follows the sequence 4, 8, 12, 16, 12, 8 and 4.
(i) 4
ii ) 6 + 2 = 8
iii) 4 + 3 + 5 =12
iv) 3 + 1 + 4 + 8 = 16
v) 2 + 6 + 4 = 12
vi) 5 + 3 = 8
viii) 4

A.21
B.15
C.13
D.1
Ans:13
Explanation:

A.0
B.4
C.11
D.13
Ans:0
Explanation:
Reading each pair of numbers in a row as a 2-digit number values are subtract by 2 and increase by 5 each time.

A.8
B.11
C.14
D.15
Ans:14

A.19
B.9
C.4
D.3
Ans:3
Explanation:
Looking at the diagram as two column numbers in the left-hand column increase by 1, 2, 3 and numbers in the right hand columns decrease by 3, 2, 1.
Left column: 2 + 1 = 3, 3 + 2 = 5, 5 + 3 = 8
Right column: 9 - 3 = 6, 6 - 2 = 4, 4 - 1 = 3

A.25
B.11
C.3
D.1
Ans:3
Explanation:
In each group of circles, the center number equals the average of the four surrounding numbers.
8 + 3 + 2 + 7 = 20, 20 / 4 = 5
12 + 13 + 6 + 5 = 36, 36 / 4 = 9
9 + 4 + 12 + 3 = 28, 28 / 4 = 7
