Answer:
500
Step-by-step explanation:
let no of books be X
2/5 th were sold ie X*2/5 = 2x/5
ie 2x/5 books were sold from X
remaining X - 2x/5 = 3x/5
from 3x/5 books 3/4 were sold
3x/5*3/4 = 9x/20
ie 9x/20 books were sold from 3x/5
remaining 3x/5-9x/20 = 3x/20 books
given3x/20 is equal to 75 books
3x/20= 75
X= 500
