Question : If $x=p+\frac{1}{p}$ and $y=p-\frac{1}{p}$, then the value of $x^{4}-2x^{2}y^{2}+y^{4}$ is:
Option 1: 24
Option 2: 4
Option 3: 16
Option 4: 8
Correct Answer: 16
Solution : $x = p+\frac{1}{p}$ $y = p-\frac{1}{p}$ Now, $x^{4}-2x^{2}y^{2}+y^{4}$ = $(x^{2}-y^{2})^{2}$ = $((x+y)(x-y))^{2}$ = $[(p+\frac{1}{p}+p-\frac{1}{p})(p+\frac{1}{p}-(p-\frac{1}{p})]^{2}$ = $[2×p×2×\frac{1}{p}]^{2}$ = 16 Hence, the correct answer is 16.
Question : The below bar graph shows the marks obtained by a student in an examination. What is the average mark obtained by the student?

Question : If $2x-2(3+4x)<-1-2x>\frac{-5}{3}-\frac{x}{3}$; then $x$ can take which of the following values?
Option 1: 1
Option 2: 2
Option 3: –2
Option 4: –1
Correct Answer: –1
Solution : Given: $2x-2(3 + 4x) < -1-2x > \frac{- 5}{3}-\frac{x}{3}$ ⇒ $2x-6-8x + 1 + 2x < 0$ and $2x - \frac{x}{3} < -1 + \frac{5}{3}$ ⇒ $-4x-5 < 0$ and $\frac{5x}{3} <\frac{2}{3}$ ⇒ $x > -5/4$ and $x < \frac{2}{5}$ Thus, $- 1.25 < x
