Question : If $x-\frac{1}{x}=1$, then what is the value of $\left (\frac{1}{x-1}-\frac{1}{x+1}+\frac{1}{x^{2}+1}-\frac{1}{x^{2}-1} \right)\;$?
Option 1: $\pm \sqrt{5}$
Option 2: $\frac{2}{5}$
Option 3: $\pm\frac{2}{\sqrt{5}}$
Option 4: $\pm\frac{\sqrt{5}}{2}$
Correct Answer: $\pm\frac{2}{\sqrt{5}}$
Solution : Given: $x-\frac{1}{x}=1$ $⇒x^{2}-1=x$ $⇒x^{2}+1=x+2$ $\left (\frac{1}{x-1}-\frac{1}{x+1}+\frac{1}{x^{2}+1}-\frac{1}{x^{2}-1} \right)$ $=(\frac{2}{x^{2}-1}+\frac{1}{x^{2}+1}-\frac{1}{x^{2}-1})$ $=(\frac{1}{x^{2}-1}+\frac{1}{x^{2}+1})$ $=(\frac{2x^{2}}{(x^{2}-1)(x^{2}+1)})$ Using $x^{2}-1=x$ and $x^{2}+1=x+2$, we get, $=(\frac{2x^{2}}{(x)(x+2)})$ $=\frac{2x}{x+2}$ Solving $x^{2}-x-1=0$, we get $x=\frac{1\pm\sqrt{5}}{2}$ So, $x+2=\frac{5\pm\sqrt{5}}{2}$ When $x=\frac{1+\sqrt{5}}{2}$, $\frac{2x}{x+2}=\frac{2}{\sqrt{5}}$ When $x=\frac{1-\sqrt{5}}{2}$, $\frac{2x}{x+2}=-\frac{2}{\sqrt{5}}$ Hence, the correct answer is $\pm\frac{2}{\sqrt{5}}$.
Question : Directions: The bar graph provided below gives the data on the production of paper (in lakh tonnes) by three different companies X, Y and Z over the years. Study the bar chart and answer the following questions.
The ratio of the average production of company X in the period 1998-2000 to the average production of company Y in the same period is:
Option 1: 27 : 29
Option 2: 23 : 25
Option 3: 25 : 26
Option 4: 24 : 27
Correct Answer: 23 : 25
Solution : As per the graph, The total production of company X in the period 1998 - 2000 = 25 + 50 + 40 = 115 lakh tonnes The number of years = 3 The average production of company X in the period 1998-2000 =
