How many days after the purchase of Product X does its standard warranty expire? (1997 is not a leap year.)

(1) When Mark purchased Product X in January 1997, the warranty did not expire until March 1997.
(2) When Santos purchased Product X in May 1997, the warranty expired in May 1997.

If someone can explain, I would be grateful.

How many days after the purchase of Product X does its standard warranty expire? (1997 is not a leap year.)

(1) When Mark purchased Product X in January 1997, the warranty did not expire until March 1997 --> warranty period can vary from 29 days (the least possible warranty: from 31st of January to 1st of March) to 89 days (the greatest possible warranty: from 1st of January to 31st of March). Not sufficient.

(2) When Santos purchased Product X in May 1997, the warranty expired in May 1997 --> warranty period can vary from 1 day (the least possible warranty: from 1st of May to 2nd of May) to 30 days (the greatest possible warranty: from 1st of May to 31st of May). Not sufficient.

(1)+(2) Intersection of the warranty periods from (1) and (2) is 29 and 30 days, still two possible answers. Not sufficient.

Answer: E.

Hope it's clear.

Hi,

Heres my take on this

Statement 1 When Mark purchased Product X in January 1997, the warranty did not expire until March 1997

Maximum coverage period 90 days (Bought on 1 Jan Expires 31 March)
Minimum Coverage period : 30 days (Bought 31 Jan Expires 1 March )

Hence insufficient

Statement 2 When Santos purchased Product X in May 1997, the warranty expired in May 1997

Maximum coverage period 30 days (Bought on 1 May Expires 31 May)
Minimum Coverage period : 0 days (Bought 1 May Expires 1 May )

Combined also the statements not going to help thus Answer is E

How many days after the purchase of Product X does its standard warranty expire?
(1997 is not a leap year.)
(1) When Mark purchased Product X in January 1997, the warranty did not expire
until March 1997.
(2) When Santos purchased Product X in May 1997, the warranty expired in May
1997.

have a doubt in this ..plz correct me

In Statement 1: Maximum validity is from 1st January to 31st March
Minimum validity is from 31st January to 1st March ( WE ARE SURE that 31st march as well as 1st march is not an expiry date HERE)

= (31 + 28 + 31) = 90 days
= (1 + 28 + 1) = 30 days

In Statement 2: (2) When Santos purchased Product X in May 1997, the warranty expired in May 1997.

Maximum possible validity of X is from 1st May to 31st may = 30 days( here we ARE ASSUMING THAT 31st is an expiry date according to the question so we cnnt include 31st day )
Minimum possible validity of X is from 1st May to 2nd May = 1 day


so the inetrsection of (1-30 ) and (30 - 90) is 30 ??

The highlighted part is not entirely correct. It will be (30+28+31) = 89 days, as you can't include 1st of January.[The question states after the day of purchase]

The minimum will occur and the no of days would be : 28+1 = 29 days.

Thus, the range of validity for the warranty : \(29\leq{w}\leq{89}\)

Similarly, from the second statement, we would have \(1\leq{w}\leq{30}\)

Combining both, we have : w=29 or w=30. Insufficient.

Hope this helps.

The maximum validity from F.S 1 :

Purchased on 1st January --> The validity starts from 2nd January.
Validity didn't expire until March(The date can not cross over to the month of April) --> 31st March, i.e. the warranty was valid till 31st March.

The total no of days from 2nd Jan to 31st March = 30(Jan)+28(Feb)+31(Mar) = 89 days.

Hence, we ARE including 31st March.

Is this better?

No. It only means that it can be valid till the last day of March and DOESN'T run into the month of April.

If I say this ticket is valid until tomorrow, will it be valid after that? It won't.

Hope this helps

Hello Bunuel,

I have a query on this solution...

I think the most confusing part here is not the calculation but understanding the meaning of 'until'
From your explanation it seems when you say until 1st of March, you are not including 1st of march while counting days....
29 days (the least possible warranty: from 31st of January to 1st of March) = 1 + 28 + 0 = 19
89 days (the greatest possible warranty: from 1st of January to 31st of March) = 31 + 28 + 30 = 89

I tried to find more on meaning of until and it seems there is no clear understanding when until date in mentioned.
PFA few links
http://www.quickanddirtytips.com/educat ... e-the-date
Above link concludes that until includes the date but recommends to consider other case also, so this is not helpful from GMAT perspective.
Its not clear from below online dictionaries as well...
http://www.thefreedictionary.com/until
http://www.macmillandictionary.com/dict ... tish/until
http://www.diffen.com/difference/Unless_vs_Until

Could you please let me know what is rule of thumb on GMAT about until ?

Thanks
jd

Apologies if this has already been discussed elsewhere, however I wonder how the question would have differed if it was mentioned as (1997 is a "Leap Year") ?

Kindly help :)

Hi - why are we finding ranges (highest difference in number of days or lowest difference in number of days)

Why are values like 2 weeks or 1 week or 20 days warranty not answer choices potentially

We want to know the warranty period in days. From (1) it can be anything from 29 days to 89 days. From (2) it can be anything from 1 day to 30 days. When combining it can be 29 or 30 days.

Now, taking the above into consideration what does your question mean?
