Yes, although a lot of people make that grammatical mixup. The correct idiom would be "The company could sell 30 cars over 30 days" if it wasn't all 30 at once.

Yes. The correct idiom would be "The company sold 30 cars over 30 days" if it wasn't all 30 at once. I could also say that " the company sold 30 cars every month, starting from January and ending in December both inclusive." I think demanding subtle language skills from the student for solving a math problem, is being unduly biased.

The difference between the past tense and the past perfect tense (if that's what it's called?) is that the former implies an action that happened at only one specific point in time.
It is called past continuous and it is not used in the way you seem to suggest.

it took me 16minutes and i still got it wrong. N it says 95:55 so why are we looking at the intervals between 9 and 9 55 only?

I guess this is not a great question. The only thing to do is guess towards the end.
If you work with the logic that there are 11 intervals in the last hour (which is what most of us did), then you reach a total value of 3210 for the number of tickets. When you try and solve for the number of regular and student tickets, you get answers in decimals, which is not possible as the number of tickets have to be integers.
At that point, there are two options:
1) Realize that there are indeed 12 intervals in the last hour as the only other possibility.
2) Carry on with the calculation which gives an answer of something around $28,845. As this falls between D and E, you guess on one and the probability of getting the question right is 50/50. Still better than nothing.
Although, the takeaway for this question is the keyword "inclusive". This word is more common when we deal with sets of consecutive integers or evenly spaced sets and are able to deal with it more easily there. But from now on, we will just have to pay more attention to it when we see it in other question types

The intervals from 9 to 9:55 have been shown only to demonstrate that every hour will have 12 intervals. There are 9 such hours. So total intervals will be 12*9

hi everyone, today this question really got me confused. and not by the "interval" nor the "inclusive" parts,
but it is the "If on one day 3 times as many regular admissions tickets were sold as student tickets" part, my interpretation of that part means that for each regular tickets there three students tickets sold, not the other way around. am I the only one here that got this wrong in this part? and can someone help explain the logic in that sentence.
thanks

thanks Consider this: You are 3 times as smart as me. Who is smarter  you or me? You are smarter, right? Similarly, "3 times as many regular admissions tickets were sold as student tickets" Regular tickets sold were more or student tickets? Regular tickets sold were 3 times so regular tickets sold were more. So there were 3 regular tickets sold for each student ticket.

Took me a little longer than I wished on this one, but here's how I came up with it: Step 1 > Set up the equation for total tickets sold. Each hour has 12 intervals to sell tickets, with a total time to sell tickets of 9 hours. 9*12=108 separate intervals to sell 30 tickets, so 30*108=3,240 total tickets. Step 2 > Set up the equation for ticket prices. Based on a ration of 3:1 I wanted to come up with an average ticket selling price. So I took (10+10+10+6)/4=9 because for every three adult tickets sold, we also sold one student ticket. On average the theater sold tickets for $9.00 each. Step 3 > Apply the two to one another. 3,240 total tickets * $9.00 average ticket price = $29,160

Let us just assume that the ticket sales was done for one hour from 9.00 AM to 10. AM  both times included. Sales happened every 5 minutes
In the above example the number of times sale happened would be 12 + 1 = 13.
Many students would forget to add the 1 at the end and hence the GMAT question setting authority had indicated that the last sale happened at 5.55 instead of at 6.00 PM.
They are really testing how quickly we can do the multiplication and splitting the total time in the ratio of 1:3 etc.
Hope this helps

Another way to solve is. First intervals 60/5=12intervals per hour. Now, from 9 to 5.55 we have 9 of such intervals hence total intervals 9*12 = 108
Then, weighted average 10$ tx and 6$ tx are in the ratio 3:1 hence weighted avg is 9$.
Hence answer will be multiple of 9, (A,D are out at this point).
9*108*30=29,160.
Answer: E

I think you need to brush up fundamentals...

Hi Bunuel, Can you help me in clarifying the number of 5 min intervals we have from 9:00 to 5:55 ? I am getting 107 intervals and not 108 from 9:00(am)to 5:00(pm) we have 8*12=96 intervals from 5:05 to 5:55 we have 11 intervals so a total of 96+11 = 107 intervals and not 108 intervals. where's the trick I am falling for ?

I got confused with the statement "3 times as many regular admission tickets were sold as student tickets". I incorrectly considered S = 3R, where S is no. of student's ticket and R is no. of regular ticket. Bunuel, is there any trick to take care of statements like "twice as many as" "thrice as many as"?

this 5 minute stuff also confused me, anyway I went on solving with 107*30, the number when divided by 4 was not going to be an integer value I understood so my results should then be adjusted UP. i calculated to the following point: 28 890 total rev  so choice E without much of moral suffering because I know I have screwed up smth, I also know I have little time and know that the figure should be actually a bit bigger, rather than smaller

Hi All, The math 'steps' behind this question can be done in a couple of different 'orders', depending on how you choose to think about the given information. Here's an approach that accounts for the difference in the price of the two types of tickets at the end of the calculation: We're told that 30 tickets are sold every 5 minutes; there are 12 'groups' of 5 minutes in each hour, so... (30)(12) = 360 tickets sold per hour (meaning from 9:00 to 9:55) From 10:00 to 10:55, another 360 tickets are sold, etc. From 9:00am to 5:55pm, we have 9 hours worth of sales... (9)(360) = 3240 total tickets IF every ticket sold cost $10, then we'd have... (3240)(10) = $32,400 HOWEVER, 1 out of every 4 tickets was actually a student ticket (which costs $6 instead of $10), so we have to subtract $4 for every student ticket in the total. (3240 total tickets)(1/4) = 820 student tickets (820 student tickets)($4) = $3280 Total revenue = $32,400 = $3280 = $29,160 Final Answer: GMAT assassins aren't born, they're made, Rich
