Question : Simplify the following. $\frac{\sin^3 \alpha+\cos^3 \alpha}{\sin \alpha+\cos \alpha}$
Option 1: $1+\sin \alpha \cos \alpha$
Option 2: $\tan \alpha$
Option 3: $1-\sin \alpha \cos \alpha$
Option 4: $\sec \alpha$
Correct Answer: $1-\sin \alpha \cos \alpha$
Solution : $\frac{\sin^3 \alpha+\cos^3 \alpha}{\sin \alpha+\cos \alpha}$ = $\frac{(\sin \alpha+\cos \alpha)(\sin^2 \alpha+\cos^2 \alpha–\sin \alpha\cos \alpha)}{\sin \alpha+\cos \alpha}$ = $(1–\sin \alpha\cos \alpha)$ [$\because \sin^2 \alpha+\cos^2 \alpha=1]$ Hence, the correct answer is $(1–\sin \alpha\cos \alpha)$.
Question : $\cos^3 60°-\cos^3 240°-\cos^3 360°=$ _________.
Option 1: $-\frac{3}{4}$
Option 2: $-\frac{7}{5}$
Option 3: $-\frac{3}{5}$
Option 4: $-\frac{9}{7}$
Correct Answer: $-\frac{3}{4}$
Solution : Given: $\cos ^3 60°-\cos ^3 240°-\cos ^3 360°$ Now, $\cos60°=\frac{1}{2}$ $\cos240°=\cos(180°+60°)=-\cos60°=-\frac{1}{2}$ $\cos360°=\cos(360°+0°)=\cos0°=1$ So, $\cos^3 60°-\cos^3 240°-\cos^3 360°$ = $(\frac{1}{2})^3-(-\frac{1}{2})^3-(1)^3$ = $\frac{1}{8}+\frac{1}{8}-1$ = $-\frac{3}{4}$ Hence, the correct answer is $-\frac{3}{4}$.
Question : There is a ratio of 5 : 4 between the two numbers. If 40 percent of the first number is 12, then 50% of the second number is:
Option 1: 12
Option 2: 24
Option 3: 18
Option 4: 20
Correct Answer: 12
Solution : Given: The ratio of two numbers = 5 : 4 Let the numbers be $5x$ and $4x$. 40% of the first number = 12 So, $\frac{40}{100}\times 5x=12$ $⇒x=6$ $\therefore$ The first number = 5 × 6 = 30 and the second number = 4 ×
