I won't give the two temperatures that the driver noticed<BR>
as he drove by the bank. (Many others will do that.)<BR>
<BR>
But if one accepts quibbling,<BR>
there would actually be a third temperature whose <BR>
digits would be reversed IF the bank's electronic<BR>
thermometer could only display two digits, and two<BR>
digits only. I will give that one: 40 dF = 04 dC.<BR>

I solved this puzzle the way I often work at Marilyn<BR>
Vos Savant's puzzles. Not by analysis of the logical<BR>
rules of the puzzle, but by assembling a mass of<BR>
data, then letting the brawn of the computer examine<BR>
the data and sort out the answer. In this case, I<BR>
used Excel, which showed that there might be a<BR>
third one...quibbling allowed.<BR>

I thought RunRev fans would enjoy the recent Car Talk puzzle. (Car <BR>
Talk is a popular American Saturday Public Radio program in the US.)<BR>
<BR>
It is particularly suited to XTalk which treats numbers as text or <BR>
numbers depending on the context.<BR>
<BR>
The local bank outdoor thermometer reports the temperature digitally <BR>
in both Celcius and Fahrenheit. One morning a driver noticed the <BR>
centigrade (Celsius) digital temperature reading on the bank <BR>
thermometer was just the reverse of the Fahrenheit digital <BR>
temperature reading.<BR>
<BR>
Driving by the bank later in the afternoon, when the weather had <BR>
cleared and warmed up, he noticed that the temperatures were higher <BR>
but once again the digits of the Centigrade and Fahrenheit readings <BR>
were reversed.<BR>
<BR>
What were the two temperatures?<BR>
<BR>
In case you have forgotten: tc = 5/9*(tf - 32)<BR>
