"Chris’s purchase criteria included screen size, which must be at least 32 inches, and price—which must not exceed $400."

There are possibly many criteria for Chris to consider. Chris cannot make a decision based on just 2 criteria.

I assumed this question is in Data Insights and not the straightforward or traditional DS questions. This is more a logical question.

The keyword is included. Therefore we can not make a definite conclusion. Option E is therefore the answer.

Why is the answer not C if we can tell from looking at both statements together that Monitor A satisfies the criteria Chris has when B clearly does not (since screen size of B is less than 32 inch)

­@sanyashah We don't know that "screen size of B is less than 32 inch". Let's review statement 2:

"(2) Monitor B cost $390 and its screen size was less than that of Monitor A."


So, we don't know that Monitor B was less than 32 inches, we just know that it was less than Monitor A. For example, A could be 40" and B could be 39" and both could satisfy the criteria.

How do we interpret the word "included" in translation of the qstem?
Could it mean that there could be more than the 2 (given) necessary criteria?

I considered only the 2 given criteria to solve the q.

Please help.

Chris was in an electronic appliances store to buy an LED computer monitor. Chris’s purchase criteria included screen size, which must be at least 32 inches, and price—which must not exceed $400. A friend made two recommendations: Monitor A and Monitor B. Chris liked both monitors. Did Chris more likely buy Monitor A, Monitor B, or neither?

(1) Monitor A’s screen size was more than 32 inches—and it cost less than Monitor B.

(2) Monitor B cost $390 and its screen size was less than that of Monitor A.

PS. This question is from the official online practice questions. It seems non-math DS questions have begun to appear just recently.

KarishmaB MartyMurray chetan2u Please help explain. Thank you in anticipation.
Ok, why is it not C? I read the thread but it is not clear to me.
Sure, A is insufficient since we do not know the cost of either of the monitors.
B as well is insufficient on its own, since B's monitor size could be 29" (< 32) or 32".
But both combined, A meets Chris' criteria.  He will likely buy A, so not "neither". What am I not understanding in the questions stem that makes C wrong? Why do we have to decide about B? This is confusing.

­Hi,

What we are given is 'two terms of reference'
1) Size> 32"
2) Cost<$400

Apart from this we do not know whether he is looking at the largest possible screen for lesser money. If that were the case, surely he would look at A.

If B does not meet the criteria in screen size, surely A is likely t o be picked.
But if B too meets the criteria in screen size, we do not whether the prefernce is for the larger screen size, so he may pick up B too because his prefernces may be dependent on some other variables when both A and B meet the cut off.

I fell for the trap of C). Are there any other questions that are as trappy as this in the OG question set? This seems so atypical of any questions I've seen. I inferred "more likely" to be "best guest with given information", but clearly the GMAT's definition of that phrase is not that loose.

The part "Note that we are not told that these are the only two criteria" is so important, it makes sense that the answer is E based on that. But from the shorter version it seemed like C

as soon as i read "Chris’s purchase criteria included screen size" i understood what all this question was about!

another thing i'd like to add that i was thinking about while solving this question --> is that the criteria are merely absolute and NOT relative. meaning that they are "true or false", there is nothing to suggest that, given two monitors that meet both the requirements, a bigger monitor is better for him, or that a lesser price is better. Both of those conclusions cannot be drawn from the statements, nor the problem text.

Thank you for the wonderful explanation!
Could you elaborate more on the “necessary condition” part? Does it mean that Chris’ choice (sufficient) -> Price&Screen size (necessary)?

So how do we interpret "more likely"? I took it to mean "from a comparative pov, based on the info provided, will he choose A over B?"

Based on the official answer guide, any question on the GMAT unless it states these are are "only" criteria means that there could be any other random criteria not answered and the answer is E for any question

PS. This question is from the official online practice questions. It seems non-math DS questions have begun to appear just recently.

Using data from both statements since either is obviously insufficient,

Monitor A: Screen size > 32 inches (Could be 33 inches or 40 inches or 50 inches); Price < $390

Monitor B
: Screen size may be < 32 or may be 35 or 40 etc (as long as it is less than that of monitor A); Price = $390


The criteria included these two but could include others too. Comparing these given criteria we are asked which is he "more likely" to buy.

Here is the problem - I don't have enough info to say because I don't know the screen size of monitor B.

Say I knew screen size of monitor B < 32 inches. Then I know he is more likely to buy A. But if both satisfy his given criteria, we don't know which he is more likely to buy. Other factors would have helped him make this decision then.

Answer (E)

so according to TTP as they have well explained in their chapter of Criteria Based DS,
we have to consider the Restricted {If the condition mentioned explicitly states only or exactly for example his only condition is or he wants exactly this} or non-Restricted group {if the condition mentioned Include just like this case or neither or if},

so in case of unrestricted group even after matching all the conditions it is not sure that buyer will buy the product, but if his conditions are from restricted group than only we can say about buyer that he will definitely buy.

I maybe wrong, but it seems as though since the GMAT has moved from the classic version to the Focus Edition, wherein Data Sufficiency is now part of a section that tests you on both "math related" and "non math related" concepts, the data sufficiency questions have gotten trickier by bringing in the CR elements into otherwise maths related questions. I think that's one part that's throwing me off, since I'm attuned to approaching the DS questions in a certain way.
