~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1.  "It took two people to complete carpeting in 10 days"  --->  it means that the entire job is 2*10 = 20 man-days.


2.  To complete it in 4 days,  = 5 workers are needed.


3.  Since you just have two workers ready, you need 5-2 = 3 additional carpenters.


Answer.  3 additional carpenters are needed.
