A survey agency reported their results in the local newspaper.

The report ststes that exactly one hundred local lawyers were interviewed.

Of the 100, seventy five own BMWs,

Ninety five own volvos and

fifty own both.

Within a short time after the report, sevral lawyers argue that the results are incorrect.

How can they tell?

The greatest challenge to any thinker is stating the problem in a way that will allow a solution.
