Please solve this sum in method and with statement

Answer 1

Answer: 1920 books

Step-by-step explanation:

Let the total no. of books be equal to =x

Hence No. of marathi books = 50/100 × x

                                                = x/2

No. of english books = (x/2) / 3

                                   = x/6

No. of maths books = (25/100)×(x/6)

                                 = (1/4) × (x/6)

                                 =x/24

Remaining no. of books = 560

Hence ,

Total no. of books = marathi books+English books+maths books+other books

i.e : x = (x/2) + (x/6) + (x/24) + 560

      x = (12x + 4x + x + 13,440) / 24

   24x= 17x + 13,440

   24x - 17x  = 13,440

              7x = 13,440

                x = 1920   ----------> ANS

Answer 2

Answer:

remember the key words. answer there in explanation.

Step-by-step explanation:

Percentage of books of Marathi=                                    50%
