Question

pls solve this question 7

Answer 1

Ratio of story books:other books = 1:7.

Let the common ratio be x.

Then, the ratio = 1x:7x.

Number of story books = 800.

1x = 800.
x = 800.

Now, we found the common ratio.

So, number of other books = 7x = 7(800) = 5600 books.

Total number of books = number of story books + number of other books = x+7x = 800+5600 = 6400 =8x.

Therefore, the total number of books in the library are 6400.

Answer 2

Let x be the story book
x=800
other book =7x=7 * 800= 5600
total books = 800+5600= 6400
