Option 1: South
Option 2: North-East
Option 3: North
Option 4: South-West

Question : The sum of a non-zero number and twice its reciprocal is $\frac{33}{4}$. Find the number.
Option 1: 9
Option 2: 10
Option 3: 11
Option 4: 8
Correct Answer: 8
Solution : Let the non-zero integer be $x$. Given: The sum of a non-zero number and twice its reciprocal is $\frac{33}{4}$. $\Rightarrow x+\frac{2}{x}=\frac{33}{4}$ $\Rightarrow 4x^2-33x+8=0$ $\Rightarrow 4x^2-32x-x+8=0$ $\Rightarrow 4x(x-8)-(x-8)=0$ $\Rightarrow (4x-1)(x-8)=0$ $\Rightarrow (4x-1)=0 \;or\;(x-8)=0$ $\therefore x=8, \frac{1}{4}$ Hence, the correct answer is 8.
Question : The value of (16 + 14) ÷ 2 – 12 + 16 × 4 – 28 + 13 (–16 + 13) is:
Option 1: 6
Option 2: 0
Option 3: –3
Option 4: 3
Correct Answer: 0
Solution : Given: (16 + 14) ÷ 2 – 12 + 16 × 4 – 28 + 13 (–16 + 13) Using the BODMAS rule we get, = 30 ÷ 2 – 12 + 16 × 4 – 28 + 13 (–3) = 15 – 12 +
Question : From the top of an upright pole $24 \sqrt{3}$ feet high, the angle of elevation of the top of an upright tower was $60^{\circ}$. If the foot of the pole was 60 feet away from the foot of the tower, how tall (in feet) was the tower?
Option 1: $84 \sqrt{3}$
Option 2: $36\sqrt{3}$
Option 3: $44\sqrt{3}$
Option 4: $60\sqrt{3}$
Correct Answer: $84 \sqrt{3}$
Solution : Here, AB = $24\sqrt3$ feet = PQ Distance, AP = 60 feet Here, AP = BQ = 60 feet In $\triangle$BQR, $\tan 60° = \frac{RQ}{BQ}$ ⇒ $\sqrt3=\frac{RQ}{60}$ $\therefore RQ = 60\sqrt3$ Height of the tower = RP = RQ + PQ = $60\sqrt3+24\sqrt3=84\sqrt3$ feet

Option 1: 5
Option 2: 6
Option 3: 7
Correct Answer: 6
Solution : Given: 121 : 12 :: 25 : ?
Like, 121 : 12; √121 = 11 and (11 + 1) = 12 Similarly, for 25 : ?; √25 = 5 and (5 + 1) = 6
So, 25 is related to 6. Hence, the second option
