Question

Pooja is twice as efficient as aarti and takes 90 days less than aarti to complete the job. Find the time in which they can finish the job together.

Answer 1

Answer:

It never happens

Step-by-step explanation:

Since Pooja is twice as efficient as aarti and takes 90 days less than aarti to complete the job, we need to find the time in which they can finish the job together.

The conclusion is that that day never happens, because when Aarti finishes in 2 days Pooja finishes in 1.

When Aarti finishes in 10 days Pooja finishes it in 5 days.

And so on.

So the conclusion is that it never happens.
