Question : If the interior of a regular polygon is 170$^\circ$, then the number of sides of the polygon is:
Option 1: 36
Option 2: 20
Option 3: 18
Option 4: 27
Correct Answer: 36
Solution : Given: If the interior of a regular polygon is 170°. Each interior angle of a regular polygon is given as $\frac{2n–4}{n}\times 90^\circ$ where $n$ is its number of sides. So, $\frac{2n–4}{n}\times 90^\circ=170^\circ$ ⇒ $\frac{2n–4}{n}\times 9=17$ ⇒ $18n-36=17n$ $\therefore n=36$ Hence, the correct answer is 36.
Question : $x$ can copy 80 pages in 20 hours $x$ and $y$ together can copy 135 pages in 27 hours. Then $y$ can copy 20 pages in:

Option 3: 24 hours
Option 4: 12 hours
Correct Answer: 20 hours
Solution : Assuming that $x$ efficiency is $e_x$ and $y$ efficiency is $e_y$. Given that $x$ can copy 80 pages in 20 hours, $⇒e_x = \frac{\text{pages}}{\text{time}} = \frac{80}{20} = 4$ Given that $x$ and $y$ together can copy 135 pages in 27 hours, $⇒e_x + e_y
