Answer:
the total number of books in the library are 9412.
Step-by-step explanation
let us total number of books in a library be x
in a library 25% books are in english
number of books are in english= 25% of x
number of english books= 0.25x
remaining books in library= x-0.25x
= 0.50x
in library 20% of the remaining books are in hindi
number of hindi books = 0.20 × 0. 50x
=0.1x
remaining books in library,
x= 0.50x - 0.1 x
= 0.05
remaining books in library are in other languages=4800
according to the question we get an equation ,
english+ hindi+ others=x
0.50x + 0.1x + 4800= x
0.51x + 4800= x
0.51x= 4800
x= 9412
