If you've heard it, stay quiet for a bit. It's a killer:

Three old ladies live together and decide to buy a new sofa. They go to the discount furniture store with 10 each, totalling 30.
They arrive at the store and find a sofa for exactly 30. They are delighted and call the salesperson over to buy it.
The sales person sells the sofa and goes to tell the manager that they got rid of the old discounted sofa. The manager is happy, but explains that the sofa came down to 25 so the sales person owes the ladies 5.
As he's walking back to them, he realises that he can't divide 5 between three people, so gives them each 1 and pockets 2 for himself. The ladies are happy that they've received a refund and the sales person is happy at getting a 2 tip.

So, the ladies paid 9 each.
The sales person had 2
3 x 9 = 27 + 2 = 29

where's the other 1?

I can see it but its frying my noodle as to why !
Must be in the way its worded !

It's not 3 x 9 = 27 + 2 - it's 3 x 9 and they've overpaid so the guy keeps the difference - so in fact it's 3 x 9 = 27 - 2 = 25.

So either 3 x 10 = 30 then take away 3 + 2 = 25

or 3 x 9 = 27 - 2 = 25.

Work this one out then

A train is trundling slowly south down the railway track at say 30 mph (the speed doesn't matter it could be anything).

A fly is flying along the track in the opposite direction (north). The fly lands on the front of the train and starts going backwards (south) it doesn't get squashed or anything the fly just lands on the front of the train.

Obviously for the fly to change direction from north to south it must have, for at least an instant, stopped to change direction (you can't go in one direction then the exact opposite without stopping first). At the time it changed direction the fly was in contact with the train, therefore the train must have stopped momentarily as well. So what happened?

Why must have?

A classic piece of misdirection.

if you use the Conservation of Momentum theory (Newton's 3rd Law), then the for them both to be stopped, the fly must have been travelling at nearly light speed to stop the train!!!

I think your tale demonstrates that you can.

Sorry Geoff, only just got back to this thread.

No, this is always a fairly quiet time of year for us - just bits n bobs - here n there Wink. Start again in earnest at the end of April.

BTW to answer your question about Hastings Pier - the answer's yes...many times, in the 70s and early 80s.

There...that should get the epz tongues wagging Wink
