Answer 1

Answer:

2:7

2X+7X=total no of books in library

           X=800

Total books=(2x800)+(7x800)

                  =7200

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Let the numbers of novels be = 2x

Let the number of other books be = 7x

number of novels = 1600( given)

2x=1600

x=1600/2

x=800

other books= 7x

7×800=5600

total number of books = novels + other books

= 1600+5600

7200

therefore total number of books = 7200
