Come up with a question and stream of consciousness reasoning that would justify this answer: 50
The question is: John buys 10 packs of magic cards. Each pack has 20 cards and 1/4 of those cards are uncommon. How many uncommon cards did he get?
Stream of consciousness: Each pack has 20 / 4 = 5 uncommons. So he got 10 * 5 = 50 uncommons.
