Answer 1

$\textbf {Hey there, here is the solution.}$
.............................................................................................
.

Virsl takes 10 days to finish the work

⇒ 1/10 of the work per day

.

Ram takes 15 days to finish the work

⇒ 1/15 of the work per day

.

Amount of work completed in a day:

Amount of work = 1/10 + 1/15 = 1/6

.

Find the number of days needed:

1/6 of the work = 1 day

6/6 of the work = 1 x 6 = 6 days

.

Answer; They will take 6 days if they worked together

.
