solution to a practical problem

[CVK]

Hello everyone,

I need a solution to a practical problem. My need is that i need to design a program for a machine. The machine takes "x"qty of load, refines 30% of it and sends back the 70% to the initial position. after how many times, does the qty of the load refined will be equal to the initial load and how many times does it need tot be refined?

after how many times, does the qty of the load refined will be equal to the initial load...?

Never unless you consider a rounding error to be a resolution.
