Question 5
Mochtar Riady building is a nine storey tall building occupying 16,000 square meters and is
home to the National University of Singapore, Business School which has 2,700 students and
also hosts six departments1. According to the2, a lift carries approximately 5 people per trip,
and each person makes 4 trips per day. Since, not all the students report to the institution each
day, assume that only 75% are in attendance, this would mean that 2,205 students use the lift
each day and in four trips. Thus, the lift would have transported 8,820 students each day.
Since there are six departments in the building, we can approximate the number of staff for
each department to be a minimum of 15, and thus the total number of staff in the building are
ninety. These staffs are likely to use the lift at least four times a day i.e. when they reporting
in the morning, when they go for lunch, when signing off and when moving between
departments. Thus, the lift will carry 360 staff in a day but in 72 trips since it can only carry 5
people at a time. Moreover, there is likely that the building receives visitors each day,
assuming that the number of visitors each day is 0.01% of the total population. Thus, the total
population carried by the lift is as computed below:
Total number of students = 8,820
Total number of staff = 360

Total number of visitors = (0.01% * (8820+360) =92
Total population carried by the lift = 8,820 + 360 +92
= 9, 272 people
Question 9
To estimate the number of people I interact within a year, I will have to consider different
factors such as the nature of my activities, personality among others. I am a University
student and attend School for five working days, attend church on one weekend and spend the
other weekend with family or doing laundry work. Being extroverted, I engage a lot3 with
students while at school and at the church in addition to the fact that I am the youth leader in
my church. The following are the number of people I interact with on a weekly basis.
School
Group discussion at school = 5 students
My friends (classmates) = 4
Waiter and cashier at the school cafeteria every lunch time = 2
My lecturers = 2
Church = 2 church leaders, 4 leaders in the youth department, and at least 20 youths
Home = my 3 siblings, 2 parents, and one neighbour
Social events on Sunday = I usually go out with my 2 siblings and sometimes with the youth
club at church (approximately 24 youths).
