The number of sociology books is 59 and the number of biology books is 177.

Step-by-step explanation:

Given,

The number of biology textbooks sold was three times the number of sociology textbooks.

Total number of books = 236

To find the number of each types of books.

Let,

The number of sociology books = x

The number of biology books = 3x

According to the problem,

3x+x = 236

or, 4x = 236

or, x = [tex]\frac{236}{4}[/tex]

or, x = 59

Hence,

The number of sociology books = 59

The number of biology books =3×59 = 177
