Answer: D

Explanation: You already know that there are 4560 students in total at the university. Since 21% of them are studying science there must be (4560/21) * 100 = 957 science students. If six percent of science students are Asian then (957/100) * 6 = 57 Asian science students.

Answer: B

Explanation: The text states that there are a total of 1049 students in the arts faculty. This represents 23% of the total number of students according to the pie-chart on the left. This means that there are 1049/23 * 100 = 4560 students in total at the university. Nine percent of students are in the Engineering faculty, and (4560/100) * 9 = 410

Answer: D

Explanation: Read the text carefully and make sure that you are clear exactly what each of these pie-charts is showing you. For example, the chart on the right shows the number of Non-US arts students. It does not show the number of art students or the percentage of Non-US arts students – both of these would be easy mistakes to make if you just
scanned the text instead of reading it carefully. There are a total of 79+21+6+2+4 = 112 Non-US arts students. The text states that there are a total of 1049 students in the arts faculty.
Therefore (112/1049) * 100 = 10.67% of the students are Non-US students.
