Para resolver este problema, primero identifiquemos las categorías que se presentan en la encuesta:

- Alumnos que toman sólo café: 12
- Alumnos que prefieren leche pero no café: 4
- Alumnos que toman otros líquidos: 8
- Alumnos que toman leche: ? (a determinar)

Recordemos que el total de alumnos encuestados es 30.

Podemos establecer la siguiente ecuación para determinar cuántos alumnos toman leche:

Alumnos que toman leche = Total de alumnos encuestados - Alumnos que toman sólo café - Alumnos que toman otros líquidos

Alumnos que toman leche = 30 - 12 - 8

Alumnos que toman leche = 30 - 20

Alumnos que toman leche = 10

Entonces, hay 10 alumnos que toman leche.
