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!!!!!!!!
