Food Industry: \[ \text{1st: Raw Material}>\text{2nd: Other Expenses}>\text{3rd: Salaries and Wages} \]
Machinery Industry: \[ \text{1st: Raw Material}>\text{2nd: Other Expenses}>\text{3rd: Salaries and Wages} \] So, in both sectors, 'Salaries and Wages' is the **third largest** expense item. \[ {\text{(d) Food \& Machinery}} \]
A bar graph shows the number of students in 5 departments of a college. If the average number of students is 240 and the number of students in the Science department is 320, how many students are there in total in the other four departments?
