Question : The value of $\frac{2 \cos ^3 \theta-\cos \theta}{\sin \theta-2 \sin ^3 \theta}$ is:
Option 1: $\sec \theta$
Option 2: $\sin \theta$
Option 3: $\cot \theta$
Option 4: $\tan \theta$
Correct Answer: $\cot \theta$
Solution : $\frac{2 \cos ^3 \theta-\cos \theta}{\sin \theta-2 \sin ^3 \theta}$ $=\frac{\cos \theta (2 \cos^2 \theta - 1)}{\sin \theta (1 - 2 \sin^2 \theta)}$ We know that $\cos2 \theta = 1 - 2\sin^2 \theta= 2 \cos^2 \theta-1$, Substituting these identities into the expression, $=\frac{\cos \theta \cos2
Question : Direction: The pie chart given below shows the percentage distribution of annual expenditure on various items of a company. The annual expenditure of the company is Rs. 72 crore. How much is the expenditure on the operation annually?
Option 1: 1.52 crore
