Question : The expenditure on the cost of living of a man and his family is 60% of his salary. He gets two increments of 30% and 60% of his salary. If his savings increase by 250% of his initial savings, then the new cost of living expenditure is what percentage (rounded off to the one digit after decimal) of the increased salary?

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
