Suppose, a litre of cola costs US$3.15. If you buy one third of a litre of cola, how much would you pay?

The above may seem like a rather basic question. Something that you would perhaps expect the vast majority of adults to be able to answer? Particularly if they are allowed to use a calculator.

Unfortunately, the reality is that a large number of adults across the world struggle with even such basic financial tasks (the correct answer is US$1.05, by the way).

[...] In many other countries, the situation is even worse. Four in every ten adults in places like England, Canada, Spain and the US can't make this straightforward calculation – even when they had a calculator to hand. Similarly, less than half of adults in places like Chile, Turkey and South Korea can get the right answer.

    Do you want to try explaining that system to people who can't work out that one third of $3.15 is $1.05 ?

    Well, they question said how much a liter costs, and asks how much 1/3rd of a liter costs. Which is a horribly stupid question, because 1/3rd of a liter would probably cost around $1.50 or even around $2 in reality.
    If you have a mathematics question, feel you have to wrap it in "everyday context" and then make it so that the "correct" answer is in complete contradiction to reality, why should I think someone is dumb because they don't give the idiotic, completely bogus answer the idiot asking was expecting?
    Sometimes, not getting the right answer means the person asking is the idiot, not the one being asked.

    Sure, the government does shit like this everyday, they just call it a Tax. You thing his scheme is convoluted compared to non linear progression of income tax, with hidden deductions sprinkled in all over the place?
