How much money can there be in a full three litre glass bottle?

Question

Ok, my mate has decided to raise some money for the local pool league to cover some of their costs.

In his wisdom he has decided to fill a three litre whisky bottle with mixed coins. A mixture he claims of our own fair currency.

There are £1 coins

and 50pences

20p's

10p's

and 5's 2's and 1s'.

We all have to guess how much money is in the bottle to win a prize.

Not the money but a £50 prize for the accurate dead on amount.

Or £25 pounds for the nearest guess.

What do you reckon the bottle holds?

How much do you think it is?

I have to make a guess so this is part of my research.

Some people are trying to do it by weight.

The whole thing weighs 2.4 stone

There are definately some pound coins but has he stashed a load where we cant see them or is it a double bluff, he has not got any pound coins we cant see?

So is the answer higher than I think or what?

Please help me.

How much do you think?

Answer 1

them things are deceiving, I'd say £365.27p

Answer 2

I have found the most accurate method of estimation is to mentally divide the bottle into four parts and then at the imaginary intersection of the quadrant give a judicious smack with a two pound hammer.

This will shatter the bottle enabling you to count the money accurately.

Remove enough money to pay for a new bottle of whiskey, then drink its contents and replace the remaining money in the empty bottle.

A  comfortable kaleidoscopic effect will then take place and the room will seem to turn to a rosy hue.

Don't panic!

When they've pumped you out and cleaned the vomit off the carpet where they found you, declare triumphantly how much is in the bottle.

It worked a treat for me.

Good luck!

Answer 3

2.4 stones means approximately 15000 g. A British penny has a mass of 3.56 g, so if it was all pennies, it would contain a bit over £42.

On the other hand, if it was all in £1 coin (with a mass of 9.5 g) it would hold £1580, over 37 times more.

The value is thus extremely dependent on the mixture of coins. Can we assume that, on average, the coin would be a 10p value?

Then the jar would contain around £200.

If I had to take a guess, that would be mine.
