E for me too..It is easy to reject the other choices but if we insist on explanation here is how i will go

we know more people have hay fever than asthma

so let us take the worst case
A = 100 people
H = 101 people

we also know that out of 100 people with asthma 95 have hay fever so teh percentage in choice E is

95/101 which is qlways less than 95% for the worst case.

D: The number of people who have both of these ailments is greater than the number of people who have only one of them
E: The percentage of people suffering from hay fever who also have asthma is lower than 95 percent
.

First thing to note is that the answer MUST be true given the facts.

A) We are told that over 95 percent of people who have asthma suffer from hay fever, so it could be 96 percent which shows that hay fever is not a prerequisite for development of asthma, as for this to even be considered the case it should be 100 percent.

B) This is similar to B, but also knowing that asthma is less common than hay fever rules this out.

C)We have no way of proving this from the data given.

D)The number of people with asthma is less common than the number of people with hay fever and 95% of these have hay fever so there is no way of proving whether this is true. As we do not know the percent of people with the more common hay fever who have asthma.

E) This is true as hay fever is much more common (read as there being a LOT more hay fever sufferers) so even if 100 percent of people who had asthma had hay fever, this would not be 95% of hay fever sufferers. Because then the statement would read that they are almost as common.

Simplified (using numbers):
Hay FeverMUCH more common than Asthma (1000 hay fever vs 100 asthma)
95% of Asthma sufferers have hay fever (95 have both)
So less than 95% who have the more common hay fever have asthma (1000 hay fever, 95 both)

Hope this helps
So less than

Thank you so much, It helps.

Look fluke, this is what I'm looking for the explaination. The link you give me doesn't provide any details but just what answer they choose. (It still makes me confused)

I think you should consider this is not the re-post, but a more detailed good post.

C: No, the population circle can be really really big, and Asthma and Hay Fever Circle combined may make a small part of its area!

E: Correct - Since Hay Fever is much more common, there a lot of people in unshared portion and this will make the number of people with both ailments 95 %.
If there was an exact number of people with Asthma, and Hay Fever, then the %age of people with Hay Fever who also have Asthma will be 95 %. As the number of people with Hay Fever is much migger than those with Hay Fever, those with both will comprise a smaller percentage of the total hay fever group.

people, who have asthma have hay fever. But who have hat fever may not have asthma. So asthma is greater than hay fever.

E sounds right as it states that hay fever is common and there are lot of sufferers .So if you take 100 percent of people who have asthma the percent of people with hay fever would be lower than 95 percent.

Since Asthma is less common than Hay Fever, than 95% of Asthma will always be less then 95% of people with Hay Fever and hence less tan 95% of the toal population. E seems the right fit.

Even if we assume the whole population has Hay Fever 95% of Asthma is less than 95% of whole population just because of the fact that Asthma is less common. We already know asthma is less so it could not comprise 95% of the population.

Not sure what am i missing here...

Fact: Asthma, a bronchial condition, is much less common ailment than hay fever, an allergic inflammation of the nasal passages.

Fact: over 95 percent of people who have asthma also suffer from hay fever.

so, lets assume Asthma people = 100

according to fact 2 over 95% of 100 suffer from hay fever...lets say 97%
that means people with hay fever & asthma = 97

now, according to fact 1, people with asthma are fewer than people with hay fever. so people with hay fever should be at least 101.

E says The percentage of people suffering from hay fever who also have asthma is lower than 95 percent

97/101 equals 96%. so we cant definitely say its below 95%

-- what am i missing here?
-- should i assume that the number of people with hay fever is much greater than 101?

If the information given as facts above is true, which of the following must also be true?

A. Hay fever is a prerequisite for the development of asthma
B. Asthma is a prerequisite for the development of hay fever
C. Those who have neither hay fever nor asthma comprise less than 5 percent of the total population
D. The number of people who have both of these ailments is greater than the number of people who have only one of them
E. The percentage of people suffering from hay fever who also have asthma is lower than 95 percent.

This problem can be done by using a Venn Diagram as well

Consider given statement: Hay fever is much more common than Asthma and over 95% of people suffering from Asthma also suffer from Hay fever

St A: I don't think so. We have people with Asthma but not hayfever (Area in yellow)
St B: We have people with Hay fever but no Asthma. (Area in red)
St C: Those who have neither...the entire white area need not be less than 5% of the total population
St D: The no. of people who have both (In Black) is not greater than the ones who have one of the dieseases
St E: % of People suffering from Hay Fever +Asthma (Black) is less than 95% percent. Yes.

People who have Asthma and Hay Fever constitute 95% of people with Asthma ie. Black Area/ Yellow+ black Area = 95%

So Black Area (both)/ Red Area (Hay Fever) has to be less than 95 as Red is greater than Yellow ie. Hayfever is more common than Asthma.
