Finding of a survey of advertisers in Systems magazine: Most of the merchandise orders placed in response to advertisements in Systems last year were placed by people under age thirty-five.

I have a problem in interpreting the argument. How can a non-subscriber have access to the magazine's advertisement?

Most of the merchandise orders placed "in response to advertisements in Systems" last year were placed by people under age thirty-five.


Should I just assume that a non-subscriber has access to magazines advertisement

Please clarify my doubt.

Finding of a survey of Systems magazine subscribers: Thirty percent of all merchandise orders placed by subscribers in response to advertisements in the magazine last year were placed by subscribers under age thirty-five.

Finding of a survey of advertisers in Systems magazine: Most of the merchandise orders placed in response to advertisements in Systems last year were placed by people under age thirty-five.

For both of the findings to be accurate, which of the following must be true?


(A) More subscribers to Systems who have never ordered merchandise in response to advertisements in the magazine are age thirty-five or over than are under age thirty-five.

(B) Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now.

(C) Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems subscribers over age thirty-five.

(D) Last year, the average dollar amount of merchandise orders placed was less for subscribers under age thirty-five than for those age thirty-five or over.

(E) Last year many people who placed orders for merchandise in response to advertisements in Systems were not subscribers to the magazine.


Hi,
First of all, I read the argument a couple to times wondering if there were a typo. Dork!!

Since both are the reports of two surveys, they are facts.
If they both have to be true, their viewers must be looking at different groups altogether.
Paradox!!
Option E reveals the same. There are definitely more people than Systems subscribers who bought the products that were advertised. For instance, people buying magazines before boarding a flight. They do not need to subscribe to buy a product advertised in the magazine. The Age of Enlightenment!!!

Please clarify my doubt.

Yes, for this passage to make sense non-subscribers must have access to the advertisements in the magazine.

The first piece of the passage deals only with subscribers who placed orders. In that group, thirty percent of those who placed orders were under 35. So, the majority of subscribers who placed orders were over 35.

The second piece of the passage deals with a wider group -- anyone who placed an order after seeing the advertisements. This would include both subscribers and non-subscribers (who perhaps looked through the magazine at their dentist's office or hair salon). In this wider group, the majority who placed orders were under 35.

I hope that helps!

Can anyone explain it? I kind of get lost when reading the question. Complex...
why E is right? I chose C instead.


Let's assume
1. A total of 100 merchandise orders were placed last year by the subscribers in response to the advertisement.
2. A total of 200 merchandise orders were received by Systems in response to the advertisement (place by non-subscribers, or in the survey's terminology - people)

Therefore, total non-subscriber (people) orders = 100

It follows from #1 that
Subscribers under 35 years old = 30 orders
Subscribers equal-to/more than 35 years old = 70 orders

Since, From stimulus: Most of the merchandise orders
placed in response to advertisements in Systems last year were placed by people under age thirty-five
,

Subscribers + Non-subscribers (people) less than 35 years old = 101 and above

Hence, the OA is "E"


Sorry mate, but I think that you assume (200 orders) what you want to show. What if there was only 100 orders?

To show this properly:
Assume 100 orders from subscribers. Then 30 orders came from (<35 and sub); and, 70 orders came from (>=35 and sub).
From statement (2) we have that most of the orders were from the people <35. So, there should be at least 41 persons (<35 and nonSub) for all the under 35s (sub+nonSub) to be a majority (30+41>70). Therefore, this is already enough to to say that "Many orders came from nonSubs".

Argument Analysis: Subscribers Survey: 30% of adv. orders placed by ppl, less than age 35. Okay, that means major orders placed by ppl over 30?
Adv. Survey: Most orders placed by ppl. under age 35.

Pre Thinking: Both statements are contradicting. Either one of the both must be lying right? 30% of orders on one set and 51-100 sample space in other set. We need some contradiction in the answer choices.

A - We are only talking about last year. This statement generalizes with the usauge of 'never'
B - We don't know anything about the current year.
C - We know only about the 30% of orders placed by ppl under 35. We cannot be sure if all / major of the orders are placed by the subscribers only.
D - But from statement 2 we know most orders are placed by people under 35. Isn't this a contradiction? Also we do not know anything about the prices, so we cannot talk about the average prices.
E - Correct. Statement 1: 30% of merchandise orders under age 35. Statement 2: 51-100 orders under age 35.. That means the major ones are those who aren't subscribers of the magazine.

The correct answer is E
