The pie charts below show the percentage of students in each faculty at North West University and the number of non-US students in the Arts faculty. These percentages have been rounded to the nearest whole number. There are a total of 1049 students in Arts faculty. Use this information to answer the following questions.
There are 34 European medical students. What percentage of the faculty does this represent?
Solution
Let the total number of students be x
Now it is given that 1049 students are in arts which is 23%
so we can say
x(23/100) = 1049
We get x =4560
Now we know that medical students = 5%
So number of medical students : 4560(0.05) = 228 students
Now out of this 34 students are European
So percentage of these with respect to total = $$\frac{34}{228}\times\ 100\ =\ 15\%$$
