20 rep to winner.

You are in a room with no doors or walls (so no way out)
You have a scale with just enough battery power to weigh something once, if you add or subtract anything from it, it will die on the spot.
There are also 10 ping pong ball making machines that make ping pong balls at 1oz
but one machine is making balls that weigh .1oz less than the others.
So how do you figure out which machine is making ping pong balls that weigh .9oz?

note, you can produce infinite amount of balls.

take 1 of the first ball then (2+3+ . . +10) of the rest of the balls if they were all the same it would weight it would be 46 oz but thats not the case if it was the 10 ball it would be 37 just multiply 0.9 x (ball amount) and you have your answer

edit: i probably just did your homework lol

46 - 0.9 x ball amount = total weight is the formula
