Saturday Puzzle - Logic needed

Last week's puzzle would normally be described as a Paradox.

But it really is NOT one.

No one came up with the right answer!

I am sure that Hashim will insist that as he was not here but in Turkey, that was why he could not answer the puzzle! Shalu in Chennai must have been on holiday! Susanna in Billinghay was probably enjoying her Sabbath week from puzzles! Dr. Gonzales was probaly mourning the loss of Brazil in the World Cup to worry about temperatures. Our 9 year old grandson, Samuel, has been away at a summer camp, far away from any computer - so I am sure he has a valid excuse!

Knowing him, I am reasonably sure he would probably have solved it. :-)

The way of answering this question is to convert 0 Celsius (C) to Fahrenheit (F).

This means the 0 C temperature is 32 F.

If it is twice as cold the next day, then it would be 16 F which converted would be -8.9 C!

So we can see that

0 x 2 = -8.9


No paradox here.

This week's puzzle will really test your logic skills.

You enter a room in which there are three light switches. These are connected individually to 3 light bulbs in the next room. You are unable to see into the second room from the first.

You can turn on and off the switches in the first room as many times you want.

How can you find out which switch belongs to which bulb, if you may enter the room with the bulbs ONLY ONCE?

Have a great week.
