Question

After selling 85 copies of a book for every 100 copies printed, a publisher finds that 450 copies are left unsold. How many copies were printed? ​

Answer 1

Answer:

3000

Step-by-step explanation:

Let the copies printed be x

Copies left after printing 100 copies = 100-85 = 15

Copies left after printing 1 copy = 15/100

Copies left after printing x copies = 15x/100

Now 450 = 15x/100

Solving the equation,

x= 3000
