## Explanation

- maximum percentage of coffee = R
- P = 300/1100 * 100 = 300/11 = 27.27%
- Q = 250/1000 * 100 = 25 %
- R = 450/1200 * 100 = 37.5 %
- S = 250/1000 * 100 = 25%
- T = 250/800 * 100 = 31.2%
- ratio of the number of students =
- Tea + Cola in S = 400 + 350 = 750
- Coffee + Cola in T = 250 + 350 = 600
- Ratio = 750/600 = 5 : 4
- ratio of number of students =
- Cola in P = 400
- Total in P = 1100
- Ratio = 400/1100 = 4/11
- percentage of students
- who drink T = 400 + 350+ 250 + 400 + 200 = 1600
- Total students = 1100 + 1000 + 1200 + 1000 + 800 = 5100
- Percentage = 1600/5100 * 100 = 1600/51 = 31.37%
- total students who drinks cola =
- 400 + 400 + 500 + 350 + 350 = 2000
