Examine the figure given below:

If Activity B takes eight days to complete instead of five days as schedule, how long can you now
delay Activity H?

A.
Three days

B.
One day

C.
Four days

D.
Zero days

Explanation:
Activity B is not on the critical path and it has a total of four days of float. If Activity B takes a total
of eight days, it will consume three days of float. However, the total duration of the path ABEHJ
may not exceed 26 days, as this is the total duration for the project. Although Activity H has a total
of four days of float available, the consumption of three days of float on this path will reduce the
total float for Activity H to just one day. If Activity H is delayed by more than one day, then the
project will be late.
Answer option D is incorrect. There is one day of float still available for Activity H.
Answer options A and C are incorrect. These are not the valid answers, as there is just one day of
float available for Activity H.
