Of the 1450 books in the library, there are 6 times as many books in the fiction section as are in the nonfiction section. Also,
guajiro [1.7K]

Number of books in non fiction section  = 200

Number of books in fiction section  = 800

Number of books in reference section  = 850

Step-by-step explanation:

Total number of books in the library = 1850

Let us assume, number of books in non fiction section = m

Number of books in fiction section= 4 x Number of books in non  fiction

= 4  x  (m)

So, the number of books in reference section = 650 + m

Now, Total Number of books =  Number of { Fiction + Non- Fiction + Reference} Books

or,  1850 =  m + (4 m)  + 650 + m

or, 6 m + 650 = 1850

⇒ 6 m = 1850 - 650 = 1200

or, m = 1200 / 6 = 200  

⇒ m = 200

Hence, the number of books in non fiction section  = 200

Number of books in fiction section  =  4 m = 4 x 200 = 800

Number of books in reference section = 650 + m  = 200 + 650 = 850
