OA to follow


I guess the OA should be C)

As out of 100x, 10x students score more than 90x students, if 10x has increased, then 100x has to increase.

Hi,

I will go with B.

A-- Out of context.
B-- If non gifted decreased gifted increased.
C-- It does not depend upon total student taking test.As if students increased we can't be sure that gifted students count increase
D-- Premise does not talked about prep.
E-- It talks about whole population -- out of context. we are talking about 14 years age students.

School Administrator: The number of fourteen year olds in Britain who are considered “gifted” – that is who score higher than 90% of their peers on the mandatory secondary school entrance exam (MSEEE) – has increased steadily over the past decade.

If the school administrator’s findings are correct, which of the following can be concluded on the basis of those findings?



Basically the sentence is: "The number of 14 yr olds scoring > 90% has increased over past decade, because...." [we have to find an answer that completes this sentence]


A)There has been at least some improvement in British education over the past decade.

B)The number of British fourteen year olds who are not considered gifted has decreased over the past decade.

C)The number of British fourteen year olds taking the MSEEE has increased over the past decade.

D)Preparation for the MSEEE has improved in British schools over the past decade.

E)The percentage of British fourteen year olds who are considered gifted has increased as a percentage of the total population.


Only C completes the sentence well: "The number of 14 yr olds scoring > 90% has increased over past decade, because the number of British fourteen year olds taking the MSEEE has increased over the past decade"

Hence ANSWER: C

actually even "c" may not be right ans....
what if the no of 14 year olds taking exam also not increasing.....it is possible....say every year 1000 took test all these years.... first year 100 , second 150, third 200 and so on scored more than 90 %......
this counters "c"......

Hi Semwal,

According to me, the argument talks about the score- which is higher than 90% of the peers.
It seems you are considering the number of the fourteen years old who scored more than 90% . (both are two different aspects)

Correct me if I am wrong.

Thanks.

I vote C too.

Only serious contenders for the answer are B and C. All others are irrelevant.
Of that, B can be easily disproved. The given statement says that the total number of 14 year olds in 90th percentile has increased. Doesnt mean that those not in the gifted group has decreased. Say initially there were 100 students and now there are 1000, both gifted and non-gifted would increase.

So only C is left.

Give kudos if you like.

Let students taking MSEE Exam 10 years ago = x
Number of gifted children 10 years ago = .10x or 10%
Number of Non gifted children 10 years ago = .90x or remaining

Let students taking MSEE Exam today = y
Number of gifted children today = .10y
Number of Non gifted children today =.90y

According to Stimulus ->

Number of gifted children today > Number of gifted children 10 years ago

or .10y>.10x
=> y > x
i.e. C)The number of British fourteen year olds taking the MSEEE has increased over the past decade.

Also notice that .85y > .85x

B)The number of British fourteen year olds who are not considered gifted has decreased over the past decade.

would have been correct if the option had "increased" instead of "decreased".

Answer - C

You can't do that. When the premise states z% of a group. You can't assume the group to be constant. Anything can happen - group can increase,decrease or remain constant, you have to account for all the possibilities. Hence, you have to take the group as a variable.
