[Charlie and the Chocolate Factory] What would happen if multiple children made it to the end and passed the Slugworth test?

Who does he give his chocolate factory to then?

Wonka *knew* the kids wouldn't make it. He studied up on the winners, and knew they were all likely to fail on certain tasks. That's why there wasn't a seat for Augustus on the Chocolate Riverboat, and why the Oompa Loompas had such quick response times for sorting out the kids who fell victim to certain hazards in the rest of the factory. Wonka knew they were flawed, and only a worthy child would inherit the factory. Anyone else was expected to lose, and hopefully gain some hindsight into what made them lose (hopefully changing them for the better in the process). 

If the kids defied all temptations and made it to the end, it's likely that Wonka would have still picked Charlie to be his successor as he was inherently a good person with not many lucky breaks in life. The rest are pretty well off, and were mostly assholes their entire lives *but* happened to put aside their temptations in order to make it through Wonka's competition. They'd leave unharmed and with a much better reward (perhaps bigger trucks of chocolate or lifetime supplies of sweets of their choosing), but Charlie still gets the factory.
