Question : If $x=\frac{1}{x-3},(x>0)$, then the value of $x+\frac{1}{x}$ is:
Option 1: $\sqrt{11}$
Option 2: $\sqrt{17}$
Option 3: $\sqrt{15}$
Option 4: $\sqrt{13}$
Correct Answer: $\sqrt{13}$
Solution : Given: $x=\frac{1}{x-3},(x>0)$ Or, $x^2-3x-1=0$ Or, $x=\frac{3\pm\sqrt{13}}{2}$ So, $x = \frac{3+\sqrt{13}}{2}$ Now, $x+\frac{1}x = \frac{3+\sqrt{13}}{2}+\frac{2}{3+\sqrt{13}}$ Rationalising, = $\frac{3+\sqrt{13}}{2}+\frac{2}{3+\sqrt{13}}\times \frac{3-\sqrt{13}}{3-\sqrt{13}}$ = $\frac{3+\sqrt{13}}{2}+2\times \frac{3-\sqrt{13}}{-4}$ = $\sqrt13$ Hence, the correct answer is $\sqrt{13}$.

Question : A train is running at a speed of 116 km/hr. The distance covered by the train (in metres) in 18 seconds is:
Option 1: 900 metres
Option 2: 1160 metres
Option 3: 508 metres
Option 4: 580 metres
Correct Answer: 580 metres
Solution : Given: The speed of the train is 116 km/hr. For converting it into m/sec, multiply with $\frac{5}{18}$. So, 116 km/hr = 116 × $\frac{5}{18}$ m/s = $\frac{580}{18}$ m/s $\therefore$ The distance covered in 18 seconds = Speed × Time = $\frac{580}{18}×18=580$ metres Hence, the
