Answer 1

Answer:

Step-by-step explanation:

Let the work be considered to have 25- units of work.

In one-day both A and B can do= 25/5= 5- units.

So in 1- day A can do3– units and B can do 2– units.

So number of days required by B to complete the work alone= 25/2= 12. 5- days.

A can complete the work alone in = 25/3= 8.33- days.
