Q1: we just have to check which is the year for wich magazine X's subscriptions were 14.6% from the right part of the first chart and we get that the total number of subscriptions is 7,000. Answer D.

Q2: we have to use the table at the bottom to compute for each year the ratio between subscriptionsof magazine z to the total and check the one most similar to 1/6=1.67. The answer is B.

Q3: To get the increase in nationwide subscriptions to any newsmagazine, we need to get the nationwide subscription for the two years of interest that can be computed using the percentage of magazine X subscriptions on the total. E.g. in 1995, the total nationwide number of subscriptions is 1.5/0.246 = 6.1 mln while in 1996, the number is equal to 2.6/0.283 = 9.2 mln. Then, the percent increase is computed as (9.2-6.1)/6.1*100 = 50.6%, rounded to 51%. Answer D.

Q4: same rationale as above. To find the nationwide number of subscription in 1998 we can use the percentage of magazine x subscriptions as 3.3/0.205 = 16.1, rounded to 16 mln. Answer C.


Why we calculate it like this 1.5/0.246 = 6.1?

Actually, in 1985, 1.5 means 1,500,000 of people are 24.6 % of what number ?? roughly 6.1 millions.

Same calculation in 1986 and we do have 9.2 million. The difference is about 50%

Hope this helps

First of all leave out the million.

Look into the first graph and 1st column : it says "Number of subscription in Thousands" :- meaning the each year the value will be = no. given * 1000
For example in the year 1995:

Number of subscription = 1.5 * 1000 = 1500

Now look into the second column of the 1st graph : it says " Number of subscriptions as a percent of nationwide subscriptions to newsmaagzine" :

let us take for the year 1995:

Number of subscriptions as a percent of nationwide subscriptions to newsmaagzine : 1500 = 24.6% of Nationwide subscription ;

or Nationwide subscription for the year 1995 =\(\frac{1500}{0.25} = 6000\) (taking 24.6% is nearly equal = 25% for easy calculation)

Hope this clears!!!!!!!!

With all due respect, I think this is complete bullshit.
This question here asks you for the "estimate number" of 1998, by forcing an "imaginary estimate" on missing data between for years 1998 and 1999.
It is true that the data in 1997 is lower than 2000, however there's no guarantee that the number in 1998 did increase.
In fact, it might have dropped in 1998, then sharply increased in 1999.

Such liberal "lump assumption" are not part of the GRE.

This is why you should be very careful when doing "questions" from books which are UNOFFICIAL and have NO ACCESS to OFFICIAL ETS guidelines on how to craft questions.
This is part of the "Princeton review".

Honestly, I have never seen such thing for any Data interpretation question.
A real GRE question is always based on actual data which cannot be interpreted non-linearly due to "missing data".
You can safely ignore this one.

OE


Quote:
In 2006, Newsmagazine z accounted for 9,400 out of 57,000 newsmagazine subscriptions. Therefore, Newsmagazine z accounted for approximately 9,000 out of 57,000, or 1/6, of the nationwide newsmagazine subscriptions.



Let me know if something is still unclear sir
