Question : A can do $\frac{7}{8}$ of work in 28 days, and B can do $\frac{5}{6}$ of the same work in 20 days. The number of days they will take to complete if they do it together is:

Option 1: $15\frac{3}{7}$ days

Option 2: $17\frac{3}{5}$ days

Option 3: $14\frac{5}{7}$ days

Option 4: $13\frac{5}{7}$ days

Team Careers360 21st Jan, 2024

Correct Answer: $13\frac{5}{7}$ days


Solution : Time taken by A alone to complete $\frac{7}{8}$ of a work = 28 days
Time taken by A alone to complete the work = $28 × \frac{8}{7}$ days = 32 days
⇒ Part of work done by A alone in a day = $\frac{1}{32}$

Question : $7 \sin ^2 A+3 \cos ^2 A=4$, then find $\cot A$:

Option 1: $\sqrt{3}$

Option 2: $\sqrt{2}$

Option 3: $\frac{1}{\sqrt{2}}$

Option 4: $\frac{1}{\sqrt{3}}$

Team Careers360 16th Jan, 2024

Correct Answer: $\sqrt{3}$


Solution : $7 \sin ^2 A+3 \cos ^2 A=4$
$7 \sin ^2 A+3(1-\sin ^2 A)=4$
$7 \sin ^2 A+3-3 \sin ^2 A=4$
$4 \sin ^2 A=1$
$ \sin ^2 A=\frac{1}{4}$
$ \sin A=\frac{1}{2}$
$\therefore A = 30^{\circ}$
$\cot A = \cot 30^{\circ} = \sqrt3 $
Hence, the
