December Mindbenders

Mixed Nuts

The nibbles for the party have been sorted – well, they had been, until little Tom decided to take twenty of the peanuts and put them in the bowl of hazelnuts.  He then mixed them up, and then randomly took twenty nuts from this bowl and put them back into the bowl of peanuts.

Are there more peanuts in the hazelnuts bowl, or hazelnuts in the peanuts bowl?
