Question : The value of $\sqrt{\frac{1+\cos A}{1-\cos A}}$ is:

Option 1: $\sec A – \tan A$

Option 2: $\operatorname{cosec} A + \cot A$

Option 3: $\sec A + \tan A$

Option 4: $\operatorname{cosec} A – \cot A$

Team Careers360 22nd Jan, 2024

Correct Answer: $\operatorname{cosec} A + \cot A$


Solution : Given, $\sqrt{\frac{1+\cos A}{1-\cos A}}$
$=\sqrt{\frac{1+\cos A}{1-\cos A}\times \frac{1+\cos A}{1+\cos A}}$
$=\sqrt{\frac{(1+\cos A)^2}{(1-\cos A)(1+\cos A)}}$
$=\sqrt{\frac{(1+\cos A)^2}{1-\cos^2A}}$ [Using $\small(a-b)(a+b)=a^2-b^2$]
$=\sqrt{\frac{(1+\cos A)^2}{\sin^2A}}$
$=\frac{1+\cos A}{\sin A}$
$=\frac{1}{\sin A}+\frac{\cos A}{\sin A}$
$=\operatorname{cosec}A+\cot A$
Hence, the correct answer is $\operatorname{cosec}A+\cot A$.

Question : A, B, and C are assigned to complete a work. If the ratio of time taken by A, B, and C is 4 : 3 : 6. Find the ratio of their efficiency.

Option 1: 3 : 4 : 2

Option 2: 4 : 3 : 6

Option 3: 3 : 4 : 6

Option 4: 4 : 6 : 8

Team Careers360 25th Jan, 2024

Correct Answer: 3 : 4 : 2


Solution : Given: the ratio of time taken by A, B and C is 4 : 3 : 6.
We know that efficiency is inversely proportional to time.
So, the ratio of their efficiency 
= $\frac{1}{4}:\frac{1}{3}:\frac{1}{6}$
= $\frac{12}{4}:\frac{12}{3}:\frac{12}{6}$ [Multiplying each ratio by 12(LCM
