Question : Two candidates A and B contested in an election. 80% of the voters cast their votes, out of which 2% of the votes were invalid. A got 9,408 votes which was 60% of the valid votes. Find the total number of votes.
Option 1: 12,000
Option 2: 22,000
Option 3: 20,000
Option 4: 21,000
Correct Answer: 20,000
Solution : Let $x$ be the total number of votes. Number of votes casted = 80% of $x$ = $\frac{80}{100}×x$ Number of invalid votes = 2% of votes cast Number of valid votes = 98% of votes cast= $\frac{98}{100}×\frac{80}{100}×x$ Number of votes A got = 60% of
Question : If $\cos\theta+\sin\theta=m$ and $\sec\theta+\operatorname{cosec \theta}=n$, then the value $n\left ( m^{2}-1 \right )$ is equal to:
Option 1: $2m$
Option 2: $mn$
Option 3: $4mn$
Option 4: $2n$
Correct Answer: $2m$
Solution : We know that $\cos\theta+\sin\theta=m$ and $\sec\theta+\operatorname{cosec \theta}=n$. $⇒n\left ( m^{2}-1 \right ) = \left(\frac{1}{\cos\theta}+\frac{1}{\sin\theta}\right)\left((\cos\theta+\sin\theta)^{2}-1\right)$ $⇒n\left ( m^{2}-1 \right ) = \left(\frac{1}{\cos\theta}+\frac{1}{\sin\theta}\right)\left(\cos^{2}\theta+2\sin\theta\cos\theta+\sin^{2}\theta-1\right)$ We know that $\cos^{2}\theta+\sin^{2}\theta=1$, $⇒n\left ( m^{2}-1 \right ) = \left(\frac{1}{\cos\theta}+\frac{1}{\sin\theta}\right)\left(2\sin\theta\cos\theta\right)$ $⇒n\left ( m^{2}-1 \right ) = 2\sin\theta\cos\theta\left(\frac{1}{\cos\theta}+\frac{1}{\sin\theta}\right)$ $⇒n\left ( m^{2}-1 \right ) =
