​

Answer 1

Answer:

Prabha can work in ==> 15 days

Ruchi can inwork ==> 10 days

Taking L C M

15 and 10 = 30units

Then prabha can work in one day => 2 Units

And Ruchi can work in one day => 3 Units

(Note : Here 2 and 3 are both efficiency)

Given :

After 2 days Ruchi give up work.

So Ruchi's work in 2 days =. 2 × 3 = 6 Units

And prabha's work => 2 × 2 = 4 Units

Then total work wil be done by both => 6 + 4

=> 10 Units

Now Remaining Units will be:

=> 30 - 20 = 20 Units

These 20 Units will be done by Prabha

because Ruchi has been left the work :

So Prabha Can the remaining work in :

=> 20/2

=> 10 Days
