Correct Answer: 10

Solution : Sum of all angles = $1440^{\circ}$
Let the number of sides of the polygon be $n$.
⇒ $1440^{\circ}$ = $(n-2)×180^{\circ}$
⇒ $(n-2)$ = $\frac{1440}{180}$
⇒ $(n-2)$ = $8$
⇒ $n$ = $2+8$ = $10$
Hence, the correct answer is 10.

Correct Answer: $\sqrt{\frac{159}{130}}$

Solution : $\sqrt{\frac{4\frac{1}{7}-2\frac{1}{4}}{3\frac{1}{2}+1\frac{1}{7}}+\frac{2}{2+\frac{1}{2+\frac{1}{5-\frac{1}{5}}}}}$
= $\sqrt{\frac{\frac{29}{7}-\frac{9}{4}}{\frac{7}{2}+\frac{8}{7}}+\frac{2}{2+\frac{1}{2+\frac{5}{24}}}}$
= $\sqrt{\frac{\frac{53}{28}}{\frac{65}{14}}+\frac{2}{2+\frac{24}{53}}}$
= $\sqrt{\frac{53}{130}+\frac{106}{130}}$
= $\sqrt{\frac{159}{130}}$
Hence, the correct answer is $\sqrt{\frac{159}{130}}$.

Correct Answer: 34,047

Solution : Let the number be $n$.
According to the question,
$\frac{4}{5} \times \frac{5}{6} \times \frac{1}{8} \times n = 4365$
$⇒\frac{1}{12} \times n = 4365$
$⇒n = 4365 \times 12 = 52380$
Now, 65% of $n = \frac{65}{100} \times 52380 = 34047$
Hence, the correct answer is

Correct Answer: Carbon Monoxide

Solution : The correct option is Carbon Monoxide.
