A man had a 10-gallon keg full of wine, and an empty jug. On Monday he drew off a jugful of wine and filled up the keg with water. On Friday, after the wine and water had been thorougly mixed, he drew off another jugful and again filled up the keg with water. The keg then contained equal quantities of wine and water.

What was the capacity of the jug?

I meant to say 1.43 - don't know what happened to the 1.

Anyway, I was figuring if you take 5 gallons over 5 days, it would average 1 gallon a day (which should be Wednesday's wine loss).

Wed's loss is only .981 gallons which throws off everything else and gives the wrong answer to the wrong question.

Using a spreadsheet to prove the 1.43 actually gave me the 1.2945 mentioned before.
