Question : If $x\sin ^{2}60^{\circ}-\frac{3}{2}\sec 60^{\circ}\tan^{2}30^{\circ}+\frac{4}{5}\sin ^{2}45^{\circ}\tan ^{2}60^{\circ}=0$, then $x$ is:
Option 1: $-\frac{1}{15}$
Option 2: $–4$
Option 3: $-\frac{4}{15}$
Option 4: $–2$
Correct Answer: $-\frac{4}{15}$
Solution : $x\sin ^{2}60^{\circ}-\frac{3}{2}\sec 60^{\circ}\tan^{2}30^{\circ}+\frac{4}{5}\sin^{2}45^{\circ}\tan ^{2}60^{\circ}=0$ $⇒x(\frac{\sqrt3}{2})^2-\frac{3}{2}×2×(\frac{1}{\sqrt3})^2+\frac{4}{5} ×\frac{1}{2}×(\sqrt{3})^2=0$ $⇒\frac{3x}{4}-1+\frac{6}{5}=0$ $⇒\frac{3x}{4}=-\frac{1}{5}$ $⇒x=-\frac{4}{15}$ Hence, the correct answer is $-\frac{4}{15}$.
Question : If $\sqrt{x}+\frac{1}{\sqrt{x}}=3, x>0$, then $x^2\left(x^2-47\right)=?$
Option 1: $0$
Option 2: $2$
Option 3: $-2$
Option 4: $-1$
Correct Answer: $-1$
Solution : As we know, $(x + \frac{1}{x})^2 = x^2 + \frac{1}{x^2} + 2$ ⇒ $(\sqrt{x} + \frac{1}{\sqrt{x}})^2 = x+\frac{1}{x} +2$ ⇒ $x + \frac{1}{x} + 2 = 3^2 = 9$ ⇒ $x + \frac{1}{x} = 9 - 2 = 7$ ⇒ $(x + \frac{1}{x})^2= 7^2$ ⇒

Question : Of the three numbers, the first is twice the second, and the second is twice the third. The average of the reciprocal of the numbers is $\frac{7}{12}$. The numbers are:
Option 1: 20, 10 and 5
Option 2: 4, 2 and 1
Option 3: 36, 18 and 9
Option 4: 16, 8 and 4
Correct Answer: 4, 2 and 1
Solution : Let us assume the third number is $x$. Second number = 2$x$ First number = 2(2$x$) = 4$x$ Reciprocals of the three numbers = $\frac{1}{4x}, \frac{1}{2x}, \frac{1}{x}$ Average of the reciprocals = $\frac{7}{12}$ Sum of the reciprocals = $\frac{1}{4x}+\frac{1}{2x}+\frac{1}{x}=\frac{7}{4x}$ Average of reciprocals
