Three students sharing digs decide to buy a television. They go down to the local tv sales shop and look at tv's. With a budget of £30 (£10 each chipped in). They find a tv at that price and take it home with them. Now, a bit later that day the manager of the shop realizes that the students have been overcharged by a fiver. He gets one of the YTS (do they still have those?) lads to take the £5 round to the students. On the way there the lad thinks to himself 'they don't know they've been overcharged, I'll keep £2 for myself and give they a pound back each'. He does this and the students are please to have only paid £9 each for the telly.

Now work it out. :think:
Three students pay £9 each for the telly 3x£9 = £27 :thumbup:
The lad keeps £2 :thumbup:
£2 + £27 = £29 :***:
Where's the other pound gone? :think: :***: :shock:
I didn't do much schooling, help.
 
Easy - TV was £25 (£30-£5) lad keeps £2 and gives £3 to the students :crazy:
 

2 from £5 is 3. £2 taken by shop assistant and one pound each for the 3 students methinks, even though I am very hot and tired :wink:

You have no idea how much this is hurting my head. It's so frustrating not being able to wrap my head around it!

Why should the amount they have paid now plus the amount the sales boy kept equal the amount they paid originally?
Here's 500 give me back 300, give 100 to someone else.
200 + 100 = 300. No reason it should be the original 500.

Not the most ideal of questions to try and get your head around when you have dyscalculia (yeah I thought it was made up too till I was told I have it :lol

Maths always has and always will baffle me!
 
Your mistake is to make the statement "they each paid £9 for the telly". This is not true..... they each paid £8.333333333 for the telly (3 times which is the £25 the shopkeeper has in the till). In addition to this they each paid 66.66666666p to the YTS yoof, (3 times which is the £2 he has in his pocket). Each of the students has £1 in his pocket that he didn't have half an hour ago, (which together make the other three pounds). It's what each person HAS that matters (Shopkeepker £25, Students £3, Yoof £2) not the erroneous "what they paid".
 

That's what I said earlier :think: Hopefully it is correct, as Maths was certainly not my best subject at school, many moons ago now:wink:

You're not the only one..... At least I don't have a career which depends solely on my maths ability.

Oh wait, yes I do

As Robert 72 points out the cost of the TV was £25 but the way the figures are presented don't add up. It is a common arithmetical trick. The way the figures should be presented is:

£25 (cost of TV) + £2 (money kept by YTS lad) = £27 (£9 donated by each of 3 students)

Here's another:

An old Bedouin tribesman dies and leaves his herd of camels to his 3 sons.

To his first son he gives half of his camels.
To his second son he gives on third of his camels.
To his third son he gives one ninth of his camels.

The problem is, he had 17 camels and you can't have one half, one third or one 9th without slicing said camels up. Whilst the sons ponder what to do a wise old man comes along on his camel and says, well, I am old and don't need mine, so I'll add it to your 17 to make up 18 camels in total.

The first son takes his half, 9 camels.
The second son takes his third, 6 camels.
The third takes his ninth, 2 camels.

The old man proclaims, but there is one left, so I can now have my old camel back.

And they all rode off into the desert. Qu'est-ce qui s'est passé? asked a passing legionaire.
 
Because a half, a third and a ninth never made a whole in the first place!

That's right. He left 17/18ths of his estate. You want a number with a few divisors and preceded by a prime. Next one for example is 23/24ths.
 
i dont have too many diabetes complications but this thread is giving me headaches and nose bleeds, i thought id left school at 13 because i was too clever for them....ummm

the worst thing is that the answers are more confusing than the questions lol
