Question : If $(y-\frac{1}{y})=-9$, what will be the value of $(y^5-\frac{1}{y^5})?$
Option 1: – 62757
Option 2: – 62748
Option 3: – 62739
Option 4: – 59049
Correct Answer: – 62739
Solution : $(y-\frac{1}{y})=-9$ Squaring on both sides, ⇒ $(y-\frac{1}{y})^2=(-9)^2$ ⇒ $y^2+\frac{1}{y^2}-2×y×\frac{1}{y}=(-9)^2$ ⇒ $y^2+\frac{1}{y^2}= 81+2= 83$ Squaring on both sides, $(y^2+\frac{1}{y^2})^2$ = $83^2$ ⇒ $y^4+\frac{1}{y^4}+2 = 6889$ ⇒ $y^4+\frac{1}{y^4} = 6887$ ⇒ $(y-\frac{1}{y})(y^4+\frac{1}{y^4})$ = $(y^5-\frac{1}{y^5}-y^3+\frac{1}{y^3})$ ⇒ $-9×6887 = (y^5-\frac{1}{y^5}-(y^3-\frac{1}{y^3}))$ ⇒ $-9×6887 = [y^5-\frac{1}{y^5}-(y-\frac{1}{y})(y^2+\frac{1}{y^2}+y×\frac{1}{y})]$ ⇒ $-61983 = [y^5-\frac{1}{y^5}-(-9)(83+1)]$
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
