Answer 2

Answer:

Given:

Pooja can water a certain garden in 4 hours while her sister aarthi can water in 3 hours. both of them start watering the garden together, but pooja leaves after 1 hour.

To find:

How much longer would it take for Aarthi to finish watering the garden?

Calculation:

Pooja takes 4 hours to water the garden, so the part of work done in 1 hour = ¼ part.

So, the amout of work left for Aarthi to do:

$1-\frac{1}{4} =\frac{3}{4} part$

Now, Aarthi can do whole work in 3 hours, so ⅓ part of work is done in 1 hour.

So, total required time for which Aarthi works

$=\frac{\frac{3}{4} }{\frac{1}{3} } hr$

=9/4hr

=2.25 hr

But, Aarthi has already worked for 1 hour with Pooja, so additional time required :

=  2.25 - 1 = 1.25 hrs

So, Aarthi has to additionally work for 1.25 hours after Pooja leaves.
