UkoKoshka [18]

Answer:

Step-by-step explanation:

The total number of teachers in the school is 100.

The who teach humanities is 25.

We want to find the number who teach Science but not Humanities.

We obtain this by subtracting the number of teachers who teach both subjects from the number that teach Science.

$= 60 - 15 = 45$
