Question : In $\triangle{XYZ}$, right-angled at $Y$, if $\sin X = \frac{1}{2}$, find the value of $\cos X \cos Z + \sin X \sin Z$.
Option 1: $\frac{\sqrt{3}}{2}$
Option 2: $\frac{\sqrt{3}}{4}$
Option 3: $\frac{2}{\sqrt{3}}$
Option 4: $\sqrt{3}$
Correct Answer: $\frac{\sqrt{3}}{2}$
Solution : Given: In $\triangle {XYZ}$, right-angled at $Y$. We know that the sum of all the angles in a triangle is 180°. $\sin X = \frac{1}{2}$ ⇒ $\sin X = \sin{30°}$ So, $\angle X = 30°$ Then $\angle Z = 60°$, because $\angle Y + \angle
Question : In an office 70% of the staff is male, 70% of the males and 30% of the females voted for Anuj. Find the percentage of the people who voted for Anuj.
Option 1: 56%

Option 4: 54%
Correct Answer: 58%
Solution : Let the total number of employees be 100. 70% are males in office = 70 70% of males voted for anuj = $\frac{70}{100}\times70 = 49$ $\therefore$ Number of females = 100 – 70 = 30 30% of females voted for anuj = $\frac{30}{100}\times30 = 9$
