Ex: (i) 3 × 1 + 4 = 7
(ii) 7 × 3 + 4 = 25
(iii) 25 × 3 + 4 = 79
(iv) 79 × 3 + 4 = 241
(v) 241 × 3 + 4 = 727

2. Can you find the missing number?

A.7
B.1
C.8
D.10
Ans: 1
Explanation:
In every row of the diagram, if you subtract the odd numbers from the even number, you always get 10.
Ex: (i) 3 + 3 = 6, 16 - 6 = 10
(ii) 9 + 3 = 12, 22 - 12 = 10
(iii) 7 + 1 = 8, 18 - 8 = 10

3. Can you find the missing number?

A.10
B.12
C.2
D.9
Ans: 2
Explanation:
Reading each row as a 3 or 2 digit number, subtract the central 2 digit value from the upper 3 digit value, to give the 3 digit result on the lower row.
Ex: 239 - 97 = 142

4. Can you find the missing number?

A.11
B.13
C.5
D.1
Ans: 1
Explanation:
In each star, the number in the center equals the difference between the sum of the even numbers and the sum of the odd numbers around the points of the star.
Ex: (i) 3 + 5 = 8, 2 + 4 + 6 = 12 ⇒12 - 8 = 4
(ii) 2 + 6 + 10 = 18, 5 + 7 = 12 ⇒18 - 12 = 6
(iii) 8 + 4 = 12, 1 + 3 + 9 = 13 ⇒13 - 12 = 1

5. Can you find the missing number?

A.26
B.29
C.27
D.30
Ans: 26
Explanation:
Starting on the top left and moving to the right then down one row and to the left, then down to the bottom row and to the right number alternately add 8 then subtract 3.
Ex: (i) 6 + 8 = 14, 14 - 3 = 11
(ii) 11 + 8 = 19, 19 - 3 = 16, 16 + 8 = 24
(iii) 24 - 3 = 21, 21 + 8 = 29, 29 - 3 = 26

6. Can you find the missing number?

A.7
B.1
C.8
D.6
Ans: 1
Explanation:
Multiply the bottom two numbers then take the square root.
Ex: (i) 3 × 12 = 36, The square root of 36 = 6
(ii) 2 × 8 = 16, The square root of 16 = 4
(iii) 1 × 4 = 4, The square root of 4 = 2

7. Can you find the missing number?

A.10
B.8
C.16
D.13
Ans: 8
Explanation:
Looking across at the circles, the number in the middle circle is the product of the two numbers in the same segment of other two circles.
Ex: 4 × 3 = 12 , 6 × 5 = 30 , 7 × 8 = 56

8. Can you find the missing number?

A.21
B.15
C.9
D.10
Ans: 10
Explanation:
Each diagonal line of numbers, starting with the top left-hand corner number, increases by 1 each time.
Ex: 4 + 1 = 5 ⇒ 3 + 2 = 5
5 + 1 = 6 ⇒ 3 + 1 + 2 = 6
6 + 1 = 7 ⇒ 2 + 2 + 1 + 2 = 7
7 + 1 = 8 ⇒ 3 + 1 + 4 = 8
8 + 1 = 9 ⇒ 4 + 5 = 9
9 + 1 = 10 ⇒ 10

9. Can you find the missing number in triangle?

A.11
B.17
C.16
D.23
Ans: 11
Explanation:
In each triangle the central value equals the sum of the 2 even numbers from the outside corners of the triangle minus the odd number.
Ex: (i) 8 + 4 = 12, 12 - 3 = 9
(ii) 2 + 6 = 8, 8 - 5 = 3
(iii) 10 + 2 = 12 , 12 - 1 = 11

10. Find the missing number in circle.

A.24
B.13
C.27
D.24
Ans: 13
Explanation:
The values in the segments of the middle circle equal the sum of the values in corresponding segments of the left- and right-hand circles.
Ex: (i) 4 + 3 = 7 , 6 + 2 = 8
(ii) 6 + 11 = 17 , 7 + 3 = 10
(iii) 10 + 8 = 18 , 9 + 4 = 13
