10 candles stand burning in a dining room. A strong breeze blows in through an open window and extinguishes 3 of them. Assuming the wind doesn't extinguish any more candles, how many candles do you have left in the end?
3. The 7 candles that manage to stay lit will melt down completely. The only candles that remain in the end are the 3 that are extinguished by the wind and therefore stay intact.
You throw away the outside and cook the inside. You eat the outside and throw away the inside. What did you eat?
