Find the missing term in each of the following:

(8)

[A] 13
[B] 15
[C] 16
[D] 19
Answer: Option [B]
Solution:

The sum of the two numbers in the upper part is seven times the number in the lower part.

i.e. (25 + 17) ÷ 7 = 6

(38 + 18) ÷ 7 = 8

So, the missing number = (89 + 16) ÷ 7 = 105 ÷ 7 = 15

(9)

[A] 30
[B] 32
[C] 34
[D] 36
Answer: Option [B]

Solution:

(5 × 6 × 4) ÷ 10 = 12

(6 × 7 × 5) ÷ 10 = 21

So, missing number = (4 × 8 × 10) ÷ 10 = 32

(10)

[A] 13
[B] 15
[C] 5
[D] 10
Answer: Option [A]

Solution:

52 + 42 = 41

62 + 72 = 85

Hence, missing number = 22 + 32 = 4 + 9 = 13

(11)

[A] 13
[B] 7
[C] 11
[D] 9
Answer: Option [A]

Solution:

(16 + 14) ÷ 2 = 30 ÷ 2 = 15

(21 + 15) ÷ 2 = 36 ÷ 2 = 18

So, (17 + x) ÷ 2 = 13 ⇒ 17 + x = 26 ⇒ x = 26 - 17 ⇒ x = 9

(12)

[A] 1
[B] 2
[C] 3
[D] 4
Answer: Option [A]

Solution:

The number at the bottom is HCF of the rest of the number.

So, missing number is = HCF of 2, 7 and 8 = 1

(13)

[A] 5
[B] 7
[C] 12
[D] 15
Answer: Option [B]

Solution:

95 - (27 + 63) = 5

79 - (38 + 37) = 4

So, missing number = 67 - (18 + 42) = 7

(14)

[A] 41
[B] 45
[C] 53
[D] 55

Answer: Option [D]

Solution:

39 = (3 × 3) + (6 × 5)

51 = (4 × 4) + (5 × 7)

So, missing number = (7 × 5) + (4 × 5) = 55
