Answer 1

Answer they complete the work in 2-3 days

Step-by-step explanation:

Answer 2

$\fontsize{18}{10}{\textup{\textbf{The required time is 2.22 days.}}}$

Step-by-step explanation:

According to the given information,

Arun can do a piece of work in 5 days, so in 1 day, Arun can do $\frac{}{}$ of the work.

Similarly, Ram can do the same work in days, so in 1 day, Ram can do $\frac{ }}$ of the work.

Therefore, in 1 day, the part of the work done by Arun and Ram is

$\dfrac{1}{5}+\dfrac{1}{4}=\dfrac{9}{20}.$

So, if Arun and Ram work together, then the time taken by them (in days) is

$\dfrac{20}{9}=2.22.$

Thus, the required time is 2.22 days.
