Five people can develop one software application in 13 days. If 2 people are suspended after the 4th day, how many total days will it take to complete the software application?

13  -  4  == 9 days' work left

 

3/5 of the work force left

 

9 / ( 3/5) ==9  x  5/3 ==45 / 3 ==15 days to finish the software application.

 

OR: 

 

[5  x  13] / 3 ==21 2/3 days to finish the 13-day job.

 

21 2/3 x 9/13 [work left] ==15 days to finish the job.
