Question : If a pole of 12 m height casts a shadow of $4\sqrt{3}$ m long on the ground, then the sun's angle of elevation at that instant is:
Option 1: 30°
Option 2: 60°
Option 3: 45°
Option 4: 90°
Correct Answer: 60°
Solution : Height of pole = 12 m Length of shadow = $4\sqrt3$ m Now, $\tan$ $\theta$ = $\frac{12}{4\sqrt3}$ ⇒ $\tan$ $\theta$ = $\frac{3}{\sqrt3}$ ⇒ $\tan$ $\theta$ = $\sqrt3$ = $\tan$ 60° ⇒ $\theta$ = 60° Hence, the correct answer is 60°.
Question : A positive number is greater than thrice its reciprocal by $\frac{26}{3}$. What is the number?
Option 1: $10$
Option 2: $11$
Option 3: $9$
Option 4: $8$
Correct Answer: $9$
Solution : Let the number be $x$. According to the question, $x\text{ – $\frac{3}{x}$ = $\frac{26}{3}$}$ or, $3x^{2} – 9= 26x$ or, $3x^{2} –26x – 9 = 0$ or, $3x^{2} + 1x –27x – 9 = 0$ or, $x(3x+1)– 9(3x+1)=0$ or, $(3x+1)(x–9)=0$ or, $x = 9, -\frac{1}{3}$
