A and B can do the work in 36 hours.
So, B can do the work alone in = $\frac{1}{\text{1 day work of A and B – 1 day work of A}}=\frac{1}{\frac{1}{36}-\frac{1}{63}}=\frac{756}{9}=$ 84 hours
Now, the

Correct Answer: Pipeline

Correct Answer: 6.5

Solution : Let the number be $x$.
According to the question,
$(x + \frac{1}{2})\times 3=21$
⇒ $(x + \frac{1}{2}) =\frac{21}{3}=7$
⇒ $x =7- \frac{1}{2}$
$\therefore x =6.5$
Hence, the correct answer is 6.5.

Correct Answer: $2,-\frac{1}{2}$

Solution : Given: $2(x^{2}+\frac{1}{x^{2}})-(x-\frac{1}{x})-7=0$
We know that, $x^{2}+\frac{1}{x^{2}} = (x-\frac{1}{x})^2+2$
⇒ $2[(x-\frac{1}{x})^2+2]-(x-\frac{1}{x})-7=0$
Put $x-\frac{1}{x}=t$
⇒ $2t^2+4-t-7=0$
⇒ $2t^2-t-3=0$
⇒ $2t^2-3t+2t-3=0$
⇒ $t(2t-3)+1(2t-3)=0$
⇒ $(2t-3)(t+1)=0$
$\therefore t=\frac{3}{2}$ or, $ -1$
Now if,
$x-\frac{1}{x}=\frac{3}{2}$
⇒ $2x^2-2=3x$
⇒ $2x^2-3x-2=0$
⇒ $2x^2-4x+x-2=0$
⇒ $2x(x-2)+1(x-2)=0$
⇒ $(x-2)(2x+1)=0$
$\therefore x = 2$ or,
