Answer me fast please ​

Answer 1

Given:

Nitin can do a piece of work in 24 days

Raman can do it in 30 days

To find:

In how  many days can they complete it, if they work together?

Solution:

Nitin alone can do a piece of work in 24 days

So, in 1 day, Nitin can do = $\frac{1}{24}$

Raman alone can do the piece of work in 30 days

So, in 1 day, Raman can do = $\frac{1}{30}$

Now,

In 1 day, both Nitin and Raman can complete,

=  $\frac{1}{24} + \frac{1}{30}$

= $\frac{5\: + \:4}{120}$

= $\frac{9}{120}$

∴ Both Nitin & Raman can complete the work in = $\frac{120}{9} = \frac{40}{3} \:days =\bold{ 13.33 \:days}$

Thus, if they work together, then Nitin and Raman will complete the work in 13.33 days.
