Find the missing term in each of the following:

(22)

[A] 250
[B] 930
[C] 390
[D] 640
Answer: Option [B]
Solution:

We have (12 + 42 + 52 + 32) × 10 = 510

(32 + 42 + 62 + 22) × 10 = 650

Hence, missing term = (42 + 22 + 82 + 32) × 10 = 930

(23)

[A] 17
[B] 19
[C] 18
[D] 11
Answer: Option [A]

Solution:

As 36, 12 is divisible by 4

and 32, 16 is divisible by 8

Similarly, 17, 17 is divisible by 17

(24)

[A] 230
[B] 125
[C] 135
[D] 209
Answer: Option [B]

Solution:

We have 82 = 64 and 83 = 512

42 = 16 and 43 = 64

Hence, missing number = 52 = 25 and 53 = 125

(25)

[A] 35
[B] 30
[C] 25
[D] 20
Answer: Option [C]

Solution:

As (18 + 17) + (9 - 6) = 38

and (12 + 12) + (8 - 3) = 29

So, the missing term = (13 + 8) + (11 - 7) = 25

(26)

[A] 101
[B] 102
[C] 103
[D] 104
Answer: Option [D]

Solution:

(27)

[A] 3
[B] 5
[C] 8
[D] 7
Answer: Option [A]

Solution:

As, 9 × 7 × 5 = 315

and 5 × 3 × 8 = 120

Similarly, 8 × 7 × ? = 168 ⇒ 168 ÷ 56 = 3

(28)

[A] 55
[B] 68
[C] 79
[D] 86

Answer: Option [B]

Solution:

As, (35 + 20 + 28) - 43 = 40

and (28 + 11 + 16) - 35 = 40

So the missing number = (25 + 35 + 40) - 32 = 68
