Step-by-step explanation:

Thus, 4x+5x+x = 15000

10x = 15000

x = 1500

Thus, English books = 4*1500=6000

Hindi books = 5*1500=7500

Urdu books = x = 1500

Answer 2

Answer:

let the numbers of book be 4x , 5x , and x

Given that total number of book is 15000

then ,

15000= 5x+4 x+ x

15000=10x

x= 15000/10

x= 1500

number of english book= 4x= 1500*4= 6000

number of Hindi book= 5x= 1500*5= 7500

number of Urdu book=x = 1500
