The number of days required for work performed only by Ms. C is: 2 days (S1) + 3 days (H1)
+ 2 days (H2) + 2 days (S2) + 2 days (S3) = 11 days.
The number of days required for work performed only by Ms. D is: 2 days (D1) + 2 days (D2)
= 4 days. However, since Ms. D performs the work concurrently with Ms. C, the number of
days is not used in the calculation.
In addition, the number of days required for work performed together by Ms. C and Ms. D is:
0.5 days (D3) + 1.5 days (S4) = 2 days.
Therefore, the number of days required for the work is 11+2=13 days.
