The Academic Computing Centre has five trainers available in its computer labs to provide training sessions to students. Assume that the de capacity of the system is $1900$ students per semester and that effective capacity equals $90\%$ of design capacity. If the number of students $w$ actually got their orientation session is $1500,$ what is the efficiency of the system?

a$.1350$ students

b$.1710$ students

C$.78\mathrm{.}9\%$

d$.90\%$

e$.87\mathrm{.}7\%$
