Answer 2

let the total number of books in library be x
then: number of English books =(30/100)×x
=3x/10
Now the number of Hindi books = =(60/100)×x
=3x/5
Now total number of Sanskrit and other languages
=(10/100)×x
=x/10
A.T.Q
25℅OFx/10=the total number of Sanskrit book
=(25/100)×(x/10)
=x/40
and x/40+52,500=x/10
=(4x/40)-(x-40)=52500

=3x/40=52,500
=17,500×40=70,000
so 10℅ of total books=52,500+70,000=1,22,500
so total number of English books=3×1,22,50=367500
total number of Hindi books = 122500×6=735000
so total number of books in library= 122500+367500+735000=12,25,000
So the total number of books in library=12,25,000
