Answer 2

Answer:

Step-by-step explanation:

Total number of student = 56

Number of student opted for mathematics = 36

Number of student opted for biology = 45

Consider the number of people taking both class are = x

Therefore,

Number of student opted only mathematics = (36-x)

Number of student opted only biology = (45-x)

Therefore,

Total number of student = (36-x)+(45-x)+x

$(36-x)+(45-x)+x=56\\\\\Rightarrow 81-x=56\\\\\Rightarrow x=81-56\\\\\Rightarrow x=25$
