in a library 20% books are English and 50 are hindi and remaining 600 are in another language what is the total no of books in the library
Answers
Step-by-step explanation:
Let the total number of books in the library be 100.
20% of these books are in Hindi = 20 books in Hindi.
Therefore the remaining books = 100 - 20 = 80 books.
50% of these remaining books are in English = 50% of 80 = 40 books.
Therefore the remaining books = 80 - 40 = 40 books.
30% of these remaining books are in French = 30% of 40 = 12 books.
Now the remaining books = 40 - 12 = 28 books.
According to the question the total remaining books = 6300.
On applying Unitary Method:-
When remaining books are 28 then total books in library = 100.
Again when remaining book is 1 then total books in the library will be = (100/28)
Therefore when remaining books are 6300 then the total books in the library
= (100/28) * 6300
= 22,500 books
Hence, the total number of books in the library = 22,500 books.
