There are several ways to approach a problem like this. 
The easiest way is to use the worker-time-job formula, which is:



where

W1 = the number of workers in the first situation.
T1 = the number of time units (days in this case) in the first situation.
J1 = the number of jobs in the first situation.

W2 = the number of workers in the second situation.
T2 = the number of time units (days in this case) in the second situation.
J2 = the number of jobs in the second situation.

W1 = 3             W2 = 2     
T1 = 4             T2 = the unknown quantity 
J1 = 2             J2 = 1











Answer: 3 days.
