myadvice this question is really fast to solve, as you have seen, provided that you avoid the pitfall of using irrelevant data. however, you can speed up your calculations a bit more, not even using the rule of three and the calculator at all, and finding the right answer in 15 or 20 seconds, by just paying some more attention to our figures. you can observe that the relation given in our exercise, 5 cases per 100 000 inhabitants, is already very close to a percentage format: we only need to divide by 1000, to get the "per 100" value. and we can mentally divide by 10, 100, 1000, etc. , in a very easy way, as you know, just moving the decimal point to the left, one place for each zero, so three times in this case, from 5 to 0. 005. 39
solution: this is a good sample exercise to apply our skills in data selection, working with percentages and avoiding irrelevant information. according to the question, we need to find a percentage of the population of cyprus: the percentage of population infected with legionellosis. so all data about the other countries are irrelevant. on the first table, regarding the incidence of this disease, we can see that there are 5 cases per 100 000 inhabitants in cyprus. how to convert this into percentage format? we can use a rule of three: if there are 5 cases per 100 000 inhabitants, then there will be x cases per 100 inhabitants. 5 100 000 x 100 5 * 100 = x * 100 000 x= 5* 100 / 100 000 = 0.005 this way we get that the incidence in percentage format for cyprus is 0.005%, so the right answer for this question is a). note that the second table is irrelevant for us, even though we can find the figure of the population of cyprus there, because if we applied our percentage to that figure, we would obtain the actual number of people affected by the disease in this country, whis not what is asked in the question (a percentage format). 38
