Three students go into a second hand shop and buy a tv for £30
They chip-in £10 each.
After they've left the kind manager notices it should have been reduced to £25. He sends the assistant after them to give them the £5.
The assistant can't be bothered dividing it into three. So he gives them £1 each and keeps £2 for himself.
So, each of the students paid £9, equals £27. The assistant has got £2, equals £29.
Where is the other pound??? |

I think the real question here is why has the assistant taken it upom himself to decide that he can't be bothered giving the correct change and will keep some himself! |

"Because they should of paid 8.33 each not £9
The other pound is in the till
Robbing bastards  "
But the fact is they DID pay £9 each because the assistant kept the other 67p x3 =£2.
The math is even simpler. They paid £27 the assistant kept two quid. The other £25 is in the till.
The trick is to ignore the £30 which actually never existed apart from on a wrong price tag! |

Yes! You win £1 !
Talking about the £30 is just to confuse things. |

Exactly, the £2 should've been taken away from the £27, not added. So the £30 is a decoy. |

They thought it was £30, but got £3 back from the naughty assistant. |

Nah, you can't fool me - you have to subtract the two pounds from the £27 - £25!!!  |

Just forget the £30, that is part of the story just to throw in the confusion.
They paid £9 each, which is £27.
£25 in the till
£2 in the assistants pocket.  |

They tricked you by adding the £2 to the £27 instead of subtracting it.
The students paid £30 and the assistant pocketed £2 and gave back £3 (£27) so only £25 went in the til. |

It's obvious:
There is 1 lb of solid + 99 lbs of water = 1% of the mass.
Later , the 1 lb is still there, but now it's 2% of the mass;
So 1 lb is 2% of... 50 lbs
So there is now 49lbs of water ; there was 99lbs of water, so 50 lbs has gone.

Maths degree person here... The trick here isn't the 30 pound... It's the fact your brain wants to think the kids paid 27 for the TVs
They didn't... The ended up paying 28 quid....
Remember they already gave 25... And then the kid gave them back another 3... And he kept 2 |

If you are going to pose the question at least know the answer
The 30 pounds isn't the red herring... It's the fact you keep saying that they paid 27 for the tele... They paid 28!
I win..... |

Think you need to check your calcs .
They originally handed over £30. They were given £3 back by the dodgy assistant. So they paid out £27.
Why do you think they paid £28??? |

Because 30 minus 2 (the assistant kept) minus 3 (3 lots of 1 quid each) equals 25 (the amount in the till) |

You're wrong, the real question is why didn't the assistant keep it all to himself, the students didn't know any better |

Up on them there hills |
The 27 pounds includes the 2 pounds they have paid, the plus the three they get back equals 30.
How it is put across would actually add up to 32.
9 x 3 = 27 + 2 (assistant) = 29 + 3 (given back) = 32 |

So forgive me I have no "maths degree" but forget there are 3 people and let's say I give you £30 and you give me £3 back which is essentially what's happened I have in fact paid out £27 ..
The original question has no meaning the sun has no relevance it's just worded to lead you into the wrong way of thinking ..the two pound he kept is bollocks if you put your 3 quid back and he put his 2 quid back it would sum up to 30 again . |
