    The total number of books in the library are 250,000

    Explanation:

    Let us suppose total number of books in a library be x

    In a library 30% books are in English

    Number of books are in English = 30% of x

    Remaining books in library = x – 0.30x = 0.70x

    In library 60% of the remaining books are in hindi

    Number of books are in Hindi = 60% of 0.70x

    Remaining books in library = x – 0.30x – 0.42x = 0.28x

    In library 25% of the remaining books are in Sanskrit.

    Number of books are in Sanskrit = 25% of 0.28x

    Remaining books in library are in other languages = 52,500

    According to question we get an equation  

    English + Hindi + Sanskrit + Other = x

    Thus, The total number of books in the library are 250,000
