Question : A can complete a piece of work alone in 120 days, while A and B, working together, can complete the same work in 72 days. In how many days can B, working alone, complete this piece of work?

Option 1: 180

Option 2: 200

Option 3: 160

Option 4: 216

Team Careers360 21st Jan, 2024

Correct Answer: 180


Solution : One day's work of A = $\frac{1}{120}$ 
One day's work of A and B together = $\frac{1}{72}$
Let B alone complete the work in b days.
One day's work of B = $\frac{1}{b}$
$\frac{1}{120}+\frac{1}{b}=\frac{1}{72}$
⇒ $\frac{1}{b}=\frac{1}{72} -\frac{1}{120}$
⇒ $\frac{1}{b}=\frac{15-9}{1080}$
⇒ $\frac{1}{b}=\frac{1}{180}$
⇒ $\therefore b=180$ days

Question : If $\sec 3 {x}=\operatorname{cosec}\left(3 {x}-45^{\circ}\right)$, where $3x$ is an acute angle, then ${x}$ is equal to:

Option 1: $45^{\circ}$

Option 2: $22.5^{\circ}$

Option 3: $35^{\circ}$

Option 4: $27.5^{\circ}$

Team Careers360 25th Jan, 2024

Correct Answer: $22.5^{\circ}$


Solution : Given that $\sec 3x = \operatorname{cosec}(3x - 45^\circ)$,
$⇒\frac{1}{\cos 3x} = \frac{1}{\sin(3x - 45^\circ)}$
$⇒\cos 3x = \sin(3x - 45^\circ)$
We know that $\sin(90^\circ - \theta) = \cos \theta$.
$⇒ 90^\circ -3x = 3x - 45^\circ$
Solving for $x$, we get:
$⇒6x = 135^\circ$
$⇒x
