    Default Maths question on a Goverment learning web site - and it's wrong!!! lol

    Just checking I'm not losing my marbles here.

    Was browsing on the BBC site and reading an article about literacy/numeracy - it had a link to the Learn Direct site where it had a couple of quizzes so I thought I'd give the Maths one a whirl. (I chose the 20 question option.)

    Question 2 stated....

    "A milk jug holds exactly one pint of milk. If one pint equals 0.568 litres, how many millilitres will it hold to the nearest hundred?"

    Options were A. 100ml B. 500ml C. 600ml D. 1100ml


    I chose B. 500ml, only to be told that I was wrong and that the correct answer was 600ml!!

    Now I understand that 600ml is the nearest hundred in terms of rounding up/down - but the question was "....how many millilitres will it hold to the nearest hundred?" How on earth can a 568ml jug (as that's what it is - clearly stated) hold 600ml?! - it can't!! The nearest hundred it can physically hold is 500ml.

    I'm not missing something here am I? - my reasoning is sound?

    I understand your reasoning but one could always argue that there is exactly one pint of milk in the jug and not 'a 1 pint jug is full of milk'. May be a case of read the question but i agree with your query.

    I think the is saying that there is a jug holding exactly 1 pint of milk, but to nearest 100ml, how many mililitres should the jug be in volume to accommodate the 568ml.

    All I can say - clumsily worded question - as most maths questions are!!!

    Well D it`s a question about numbers.....not logic....I get you point, but it`s just a matter of going from LitTer to Ml. and then rounding it up...yeah you are right 600 ml. wont fitt on a 568 bottle

    Yep, can see your reasoning there, although the first part of the question...."A milk jug holds exactly one pint of milk" to me says that it only capable of holding a pint, as opposed to it currently holds a pint but can hold more.

    Yep! As you say it may not be implying that the jug holds a maximum of a pint, merely what it's currently holding! Very badly worded question!!

    In maths you are always told the rule greater than 0.5 round up, less than 0.5 round down unless circumstances make rounding in a certain situation impossible. If you in exam and chose the 500ml, with an explanation to the side you would get some or all of the marks because you would be demonstrating you understand these circumstances in this question.

    But in all honesty I doubt anyone can fault your finding.

    Yep, that's what I was saying. I totally agree that the 600ml answer is the nearest 100ml using the rounding up/down method - straightforward. As you've seen, my 'issue' was that they implied that the jug held exactly a pint (568ml) so the nearest 100ml it could hold would be 500ml as it physically couldn't hold 600ml.

    Just a very badly worded question if they weren't meaning the jug could only hold a pint. Can I be arsed to e-mail them? - nah, sod that!!

    Too early in the morning for this, in the context of the question 600ml is correct. In the real world 500ml would be correct.

    I've just done a quick Mensa test and considering the time of night (or morning) got 28 out of 30

    It is hard to think straight when it's done correctly against the clock.

    The question and answer are both correct, based on the grammar

    I see your logic D.

    I guess their arguement is that the jug will hold 568 ml. If the jug is holding 568 ml then to the nearest 100 its holding 600 ml.

    Sorry D, but the answer is indeed 600ml. Rounding 568 to the nearest 100 would be to 600. I've got an 'A' Level in maths, but that may not be enough....

    Since when has maths been logical??
