1. Which number replaces the question mark?

A.29
B.28
C.27
D.24
Ans:24
Explanation:
The left number multiplied by 5 gives the total of the other two.
Ex : The product is 27 x 5 = The sum of 56 + 79. The answer becomes equal.
(i) 27 * 5 = 56 + 79 = 135,
(ii) 23 * 5 = 88 + 27 = 115
, (iii) 16 * 5 = 56 + 24 = 80

2. Which number replaces the question mark?

A.27
B.25
C.18
D.27
Ans:18
Explanation:
In each circle, the number in the lower segment equals the sum of upper two numbers and the answer with product 2 and get the final answer.
Ex : (i) 5 + 2 = 7, 7 * 2 = 14
(ii) 9 + 1 = 10, 10 * 2 = 20
(iii) 4 + 3 = 7, 7 * 2 = 14
(iv) 2 + 7 = 9, 9 * 2= 18

3. Which number replaces the question mark?

A.15
B.18
C.31
D.5
Ans:5
Explanation:
Working through the diagram in rows, add the left and central numbers together and subtract 2 to give the right-hand value.
Ex: (i) 6 + 1 = 7, 7 - 2 = 5
(ii) 3 + 9 = 12, 12 - 2 = 10
(iii) 4 + 3 = 7, 7 - 2 = 5

4. Which number replaces the question mark?

A.9
B.12
C.16
D.19
Ans:16
Explanation:
Starting bottom left and moving clockwise around the triangle, numbers follow the sequence of Square Numbers.
Ex : 1 * 1 = 1, 2 * 2 = 4, 3 * 3 = 9, 4 * 4 = 16, 5 * 5 = 25, 6 * 6 = 36, 7 * 7 = 49, 8 * 8 = 64, 9 x 9 = 81

5. Which number replaces the question mark?

A.4
B.3
C.2
D.1
Ans:4
Explanation:
Working in columns, the sum of the numbers in each column is always 14.
Ex : (i) 7 + 2 + 1 + 4 = 14
(ii) 3 + 8 + 1 + 2 = 14
(iii) 6 + 5 + 2 + 1 = 14
(iv) 2 + 4 + 4 + 4 = 14

6. Which number replaces the question mark?

A.7
B.25
C.21
D.9
Ans:9
Explanation:
In each triangle of the diagram, the sum of the numbers is always 22.
Ex : (i) 2 + 4 + 7 + 9 = 22
(ii) 11 + 3 + 6 + 2 = 22
(iii) 5 + 6 + 5 + 6 = 22
(iv) 1 + 2 + 17 + 2 = 22
(v) 1 + 1 + 19 + 1 = 22
(vi) 8 + 1 + 4 + 9 = 22

7. Which number replaces the question mark?

A.23
B.26
C.24
D.28
Ans:23
Explanation:
Starting top left, and moving down in columns from left to right, the numbers follow the sequence of Prime Numbers from 2 to 23.
Ex : Sequence of prime number : 2, 3 , 5 ,7, 11, 13, 17, 19, 23

8. Find the missing number in question?

A.12
B.5
C.11
D.15
Ans:5
Explanation:
In each star, the central number equals the difference between the sum of the even numbers and the sum of the odd numbers from the points of the star.
Ex : (i) 4 + 2 + 6 = 12, 3 + 1 = 4, 12 - 4 = 8
(ii) 4 + 8 + 2 = 14, 11 + 9 = 20, 20 - 14 = 6
(iii) 10 + 2 = 12, 7 + 5 + 5 = 17, 17 - 12 = 5

9. Find the missing number in question?

A.4
B.7
C.1
D.0
Ans:4
Explanation:
Working in columns, the sum of the numbers in each column is always 20.
Ex : (i) 7 + 3 + 5 + 5 = 20
(ii) 8 + 2 + 3 + 7 = 20
(iii) 9 + 1 + 4 + 6 = 20
(iv) 11 + 3 + 2 + 4 = 20

10. Find the missing number in question?

A.6
B.2
C.9
D.7
Ans:7
Explanation:
In each row of the diagram, the central value equals the sum of the differences between the left-hand pair of numbers and the right-hand pair of numbers.
Ex : (i) 4 - 1 = 3, 11 - 3 = 8 , 8 + 3 = 11
(ii) 3 - 3 = 0, 6 - 5 = 1, 0 + 1 = 1
(iii) 9 - 2 = 7, 4 - 2 = 2, 7 + 2 = 9
(iv) 6 - 4 = 2, 9 - 3 = 6, 2 + 6 = 8
(v) 5 - 1 = 4, 4 - 1 = 3 , 4 + 3 = 7
