Question : If $(\frac{\sec \theta-1}{\sec \theta+1})^n=\operatorname{cosec} \theta-\cot \theta$, then $n=?$

Option 1: 1

Option 2: 0.5

Option 3: –1

Option 4: –0.5

Team Careers360 18th Jan, 2024

Correct Answer: 0.5


Solution : Given expression,
$(\frac{\sec \theta-1}{\sec \theta+1})^n=\operatorname{cosec} \theta-\cot \theta$
Considering L.H.S.,
We know, $\sec\theta=\frac{1}{\cos\theta}$
= $\left\{\frac{\frac{1}{\cos\theta}-1}{\frac{1}{\cos\theta}+1}\right\}^n$
= $\left\{\frac{1-\cos\theta}{1+\cos\theta}\right\}^n$
Multiplying and dividing by $1-\cos\theta$, we get,
= $\left\{\frac{1-\cos\theta}{1+\cos\theta}\times\frac{1-\cos\theta}{1-\cos\theta}\right\}^n$
= $\left\{\frac{(1-\cos\theta)^2}{1-\cos^2\theta}\right\}^n$
= $\left\{\frac{(1-\cos\theta)^2}{\sin^2\theta}\right\}^n$
Now consider R.H.S,
$\operatorname{cosec} \theta-\cot \theta$
We know, $\operatorname{cosec} \theta=\frac{1}{\sin\theta}$ and $\cot\theta=\frac{\cos\theta}{\sin\theta}$
= $\frac{1}{\sin\theta}-\frac{\cos\theta}{\sin\theta}$
= $\frac{1-\cos\theta}{\sin\theta}$

Question : In a survey, 200 respondents were asked whether they owned a vehicle or not. Their responses are tabulated below.
What percentage of respondents do NOT own a car?

  Men Women
Own Vehicle Scooter 30 20
Car 25 10

Option 2: 75%

Option 3: 65%

Option 4: 72.5%

Team Careers360 21st Jan, 2024

Correct Answer: 72.5%


Solution : Given: In a survey, 200 respondents were asked whether they owned a vehicle or not.
The percentage of respondents who do not own a car
$=\frac{\text{Total respondents who do not own a car}}{\text{Total respondents}}×100=\frac{30+50 + 20 + 45}{200}\times 100=\frac{145}{200}=72.5\%$
Hence, the correct answer is 72.5%.
