Answer: (b)

$(60 + 61)^{1/2}$ - $(45 + 55)^{1/2}$ = 11 - 10 = 1

$(82 + 87)^{1\2}$ - $(49 + 32)^{1/2}$ = 13 - 9 = 4

$(79 + 65)^{1/2}$ - $(37 + 12)^{1/2}$ = 12 - 7 = 5

Answer: (d)

We have : √36 + √64 + √25 + √49 = 26;

√9 + √25 + √16 + √81 = 21

So, missing number

= √25 + √144 + √36 + √64 = (5 + 12 + 6 + 8) = 31

Answer: (a)

In the squares on the corners–

Product of left two numbers = product of right two numbers.

i.e., 4 × 9 = 12 × 3,

8 × 5 = 4 × 10

5 × 16 = 8 × 10

∴ 9 × 8 = 6 × ?

⇒ ? = ${9 × 8}/6$ 12.

Answer: (c)

In the first row, $72 ÷ (24/2) = 72 ÷ 12 = 6$

In the second row, $96 ÷ (16/2) = 96 ÷ 8 = 12$

Let the missing number in the third row be x. Then,

$108 ÷ (X/2) = 18 ⇒ X/2 = {108}/{18} = 6 ⇒ X = 12$

Answer: (b)

In first figure : (25 + 17) ÷ 6 = 7

In second figure : (38 + 18) ÷ 8 = 7

there4; (89 + 16) ÷ ? = 7

⇒ 105 ÷ ? = 7

⇒ ? = ${105}/{7}$ = 15
