1. Find the number that replaces the question mark?

A.10
B.6
C.1
D.8
Ans:8
Explanation:
So that each square block of four numbers totals 20.
Ex : 8 + 7 + 4 + 1 = 20, 5 + 10 + 2 + 3 = 20, 1 + 4 + 7 + 8 = 20.

2. Find the number that replaces the question mark?

A.55
B.60
C.59
D.65
Ans:59
Explanation:
Moving from left to right, numbers follow the sequence of square numbers, from 4, 5, 6, 7, 8 subtracting 5 each time.
Ex : 4 * 4 = 16 - 5 = 11
5 * 5 = 25 - 5 = 20
18 * 18 = 36 - 5 = 31
7 * 7 = 49 - 5 = 44
8 * 8 = 64 - 5 = 59

3. Find the number that replaces the question mark?

A.4
B.7
C.11
D.3
Ans:4
Explanation:
In each row of each grid, multiply the left- and right-hand numbers together to give a digit value and write this value in the two center boxes.
Ex : (i) 8 * 7 = 56
(ii) 12 * 5 = 60
(iii) 16 * 4 = 64

4. Find the number that replaces the question mark?

A.37
B.40
C.42
D.45
Ans:42
Explanation:
In a given pyramid, add two consecutive numbers from the left of the bottom side. The same will follow to next consecutive numbers and for the remaining rows.
Ex :22 + 20 = 42, 13 + 9 = 22, 11 + 9 = 20
7 + 6 = 13, 6 + 3 = 9, 8 + 3 = 11
4 + 3 = 7, 4 + 2 = 6, 1 + 2 = 3, 7 + 1 = 8

5. Find the number that replaces the question mark?

A.17
B.19
C.16
D.13
Ans:16
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) 7 + 4 + 1 = 12, 5 + 2 = 7 ⇒ 12 - 7 = 5
(ii) 6 + 3 + 8 = 20, 0 + 9 = 9 ⇒ 20 - 9 = 11
(iii) 10 + 7 + 5 = 22 , 4 + 2 = 6 ⇒ 22 - 6 = 16

6. Find the number that replaces the question mark?

A.0
B.9
C.12
D.8
Ans:9
Explanation:
Taking any side of the triangle, the sum of the two corner digits is written in one of the circles on that side, and the difference is written in the other circle.
Ex : (i)19 + 5 = 24, 19 - 5 = 14
(ii) 19 + 9 = 28, 19 - 9 = 10
(iii)9 + 5 = 14, 9 - 5 = 4.

7. What number should replace the question mark with answer?

A.13
B.17
C.16
D.19
Ans:13
Explanation:
Starting with the bottom line of the triangle and moving up, the sum of the digits in each line decreases by 5 each time, from 25 to 10.
Ex : 10, 8 + 7 = 15, 9 + 8 + 3 = 20, 6 + 4 + 2 + 13 = 25

8. What number should replace the question mark with answer?

A.9
B.7
C.5
D.10
Ans:5
Explanation:
In each diagram, the sum of the three upper numbers equals the product of the two lower numbers.
Ex : (i) 9 + 6 + 6 = 21, 7 * 3 = 21
(ii) 13 + 5 + 6 = 24, 6 * 4 = 24

9. What number should replace the question mark with answer?

A.9
B.8
C.7
D.6
Ans:7
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 grey segment
Ex :(i)6 * 2 = 12, 4 + 4 = 8 ⇒ 12 - 8 = 4
(ii)5 * 5 = 25, 7 + 3 = 10 ⇒ 25 - 10 = 15
(iii)4 * 3 = 12, 5 + 2 = 7 ⇒ 12-7 = 5
(iv)3 * 6 = 18, 5 + 4 = 9 ⇒ 18 - 9 = 9
(v)4 * 4 = 16, 6 + 2 = 8 ⇒ 16 - 8 = 8
(vi)7 * 3 = 21, 5 + 5 = 10 ⇒ 21 - 10 = 11
(vii)5 * 2 = 10, 4 + 3 = 7 ⇒ 10 - 7 = 3
(viii)5 * 4 = 20, 4 + 3 = 7 ⇒ 20-9=7

10. What number should replace the question mark with answer?

A.5
B.9
C.1
D.10
Ans:9
Explanation:
Starting with the top left square, and moving clockwise around the other 3, the sum of the digits in each square follows the sequence 20, 19, 18, 17.
Ex : (i) 2 + 3 + 6 + 9 = 20
(ii) 6 + 7 + 3 + 3 = 19
(iii)1 + 3 + 9 + 5 = 18
(iv) 9 + 1 + 1 + 6 = 17
