Answer: Option [B]

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

(3² + 4² + 6² + 2²) × 10 = 650

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

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

Answer: Option [B]

Solution:

We have 8² = 64 and 8³ = 512

4² = 16 and 4³ = 64

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

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

Answer: Option [D]

Solution:

Answer: Option [A]

Solution:

As, 9 × 7 × 5 = 315

and 5 × 3 × 8 = 120

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

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
