Option 4: 20%
Correct Answer: 18.75%
Solution : Initial value = INR 40960 Value after depreciation = INR 21970 Time = 3 years Ratio of initial value and final value = $\sqrt[n]{\text{Initial value}}:\sqrt[n]{\text{Depreciated value}}$ = $\sqrt[3]{40960}:\sqrt[3]{21970}$ = $\sqrt[3]{4096}:\sqrt[3]{2197}$ = $16 : 13$ Difference = 16 – 13 = 3 Required percentage = $\frac{\text{Difference}}{\text{Initial

Question : If $\cos \theta+\sec \theta=2$, then the value of $\sin ^6 \theta+\cos ^6 \theta$ is:
Option 1: $\frac{1}{3}$
Option 2: $0$
Option 3: $1$
Option 4: $\frac{1}{2}$
Correct Answer: $1$
Solution : Given that $\cos \theta + \sec \theta = 2$, $⇒\cos \theta + \frac{1}{\cos \theta} = 2$ $⇒\cos^2 \theta + 1 = 2\cos \theta$ $⇒\cos^2 \theta - 2\cos \theta + 1 = 0$ $⇒(\cos \theta - 1)^2 = 0$ $⇒\cos \theta = 1$ $⇒\theta=0°$ $⇒\sin \theta
