Question : The interior angle of a regular polygon exceeds its exterior angle by 108$^\circ$. The number of the sides of the polygon is:
Option 1: 12
Option 2: 16
Option 3: 14
Option 4: 10
Correct Answer: 10
Solution : Given that the interior angle of a regular polygon exceeds its exterior angle by 180$^\circ$. For a regular polygon, each exterior angle = $\frac{360^\circ}{n}$ And each interior angle = $\frac{180^\circ\times (n-2)}{n}$ So, $\frac{180^\circ\times (n-2)}{n}-\frac{360^\circ}{n}=108^\circ$ Or, $180^\circ\times n-108^\circ\times n=720^\circ$ Or, $n=10$ Hence, the correct answer is
Question : The percentage of nitrogen present in ammonium sulphate is:

Question : The value of $(x^{\frac{1}{3}}+x^{-\frac{1}{3}})(x^{\frac{2}{3}}-1+x^{-\frac{2}{3}})$ is:
Option 1: $x^{-1}+x^{\frac{2}{3}}$
Option 2: $x+x^{-\frac{1}{3}}$
Option 3: $x^{\frac{1}{3}}+x^{–1}$
Option 4: $x+x^{–1}$
Correct Answer: $x+x^{–1}$
Solution : Given: $(x^{\frac{1}{3}}+x^{-\frac{1}{3}})(x^{\frac{2}{3}}-1+x^{-\frac{2}{3}})$ $=x^{\frac{1}{3}}×x^{\frac{2}{3}}-x^{\frac{1}{3}}+x^{\frac{1}{3}}×x^{-\frac{2}{3}}+x^{-\frac{1}{3}}×x^{\frac{2}{3}}-x^{-\frac{1}{3}}+x^{-\frac{1}{3}}×x^{-\frac{2}{3}}$ $=x^{\frac{1}{3}+\frac{2}{3}}-x^{\frac{1}{3}}+x^{\frac{1}{3}-\frac{2}{3}}+x^{-\frac{1}{3}+\frac{2}{3}}-x^{-\frac{1}{3}}+x^{-\frac{1}{3}-\frac{2}{3}}$ $=x^1-x^{\frac{1}{3}}+x^{-\frac{1}{3}}+x^{\frac{1}{3}}-x^{-\frac{1}{3}}+x^{-1}$ $=x+x^{-1}$ Hence, the correct answer is $x+x^{-1}$.
