Question : A certain number of men completed a piece of work in 60 days. If there were 8 men more, the work could be finished in 10 days less. The number of men originally was:

Option 1: 36

Option 2: 40

Option 3: 30

Option 4: 32

Team Careers360 25th Jan, 2024

Correct Answer: 40


Solution : Given:
Let the original no of men be $x$.
$x$ men can finish it in 60 days,
and $(x+8)$ men can finish in 50 days.
$M_{1}D_{1}=M_{2}D_{2}$, where $M_1$ and $M_2$ are men and $D_1$ and $D_2$ are days.
$⇒60x = 50(x+8)$
$⇒10x= 400$
$\therefore x

Question : If $ \frac{k-k \cot ^2 30^{\circ}}{1+\cot ^2 30^{\circ}}=\sin ^2 60^{\circ}+4 \tan ^2 45^{\circ}-\operatorname{cosec}^2 60^{\circ}$, then the value of k (correct to two decimal places) is:

Option 1: 5.55

Option 2: – 6.83

Option 3: – 5.58

Option 4: 6.83

Team Careers360 25th Jan, 2024

Correct Answer: – 6.83


Solution : Computing RHS,
$\sin ^2 60^{\circ}+4 \tan ^2 45^{\circ}-\operatorname{cosec}^2 60^{\circ} = (\frac{\sqrt{3}}{2})^2+4\times1^2-(\frac{2}{\sqrt{3}})^2$
⇒ $\sin ^2 60^{\circ}+4 \tan ^2 45^{\circ}-\operatorname{cosec}^2 60^{\circ} = \frac{3}{4}+4-\frac{4}{3}$
⇒ $\sin ^2 60^{\circ}+4 \tan ^2 45^{\circ}-\operatorname{cosec}^2 60^{\circ} = \frac{41}{12}$
Computing LHS,
$ \frac{k-k \cot ^2 30^{\circ}}{1+\cot ^2 30^{\circ}} = k(\frac{1- (\sqrt{3})^2}{1+(\sqrt{3})^2})$
⇒
