The students of a class drink different beverages; A, B, and C. A total of 100 students drink A, 150 drink B and 200 drink C.

| C Only | 13:12 |
| A & B only | 4:1 |
| A & C only | 7:8 |
| B & C only | 1:4 |
| A, B & C | 3:1 |
C = 200
100+20+(40-x)+(60-x) = 200
40-x+60-x = 200-120
100 – 2x = 80
100 – 80 = 2x
x = 10
