There are books in a library, there are 4 different kinds of books. Science books make up 3/4 of art books. Comic books are 1/4
Sergeeva-Olga [200]

Answer:

The total number of books is 1020.

Step-by-step explanation:

Denote the books by their first letter.

From the provided information:

  • S=\frac{3}{4}A
  • C=\frac{1}{4}T
  • H=\frac{1}{5}T
  • H = A-80

Compute the expression of <em>T</em> as follows:

H = A-80\\\\\frac{1}{5}T=A-80\\\\T=5A-400...(i)

Compute the value of <em>C</em> in terms of <em>A</em>:

C=\frac{1}{4}T\\\\C=\frac{1}{4}\times {5A-400}\\\\C=\frac{5}{4}A-100...(ii)

Compute the value of <em>A</em> as follows:

Use expressions (i) and (ii):

T=S+C+H+A\\\\5A-400=\frac{3}{4}A+\frac{5}{4}A-100+A-80+A\\\\5A-400=4A-180\\\\A=220

Compute the value of <em>T</em> as follows:

T=5A-80\\\\T=(5\times 220)-80\\\\T=1100-80\\\\T=1020

Thus, the total number of books is 1020.
