DAILY TRAIN SCHEDULE Train X Scheduled Departure Station S at 7:08 (EST)* Scheduled Arrival Station T at 8:10 (EST)

The table above shows the morning schedule for train X . If Juan took train X on Monday morning, did he arrive at station T on schedule?

(1) Juan arrived at station T on Monday morning 1 hour and 2 minutes after he left station S . (2) Juan arrived at his office at 8:30 (EST) on Monday morning, which was 20 minutes after he arrived at station T .

1) 1 hour and 2 minutes is exactly the time between departure and arrival according to the schedule so this means he arrived when he was supposed to.

2) He arrived at his office at 8:30 which was 20 minutes after he arrived at the station so he was at the station 8:10 which again is the time in the schedule.

The first statement says- "Juan arrived at station T on Monday morning 1 hour and 2 minutes after he left station S"

Suppose the train started on 7:20, so he will arrive on T at 8:22, which is not on schedule. Again it can start on time and arrive T on time, so 1 is not sufficient.

From 2, you can get that he arrived at station T at 8:10 (8:30 less 20 mins), so it is on time. Hence B is the answer.

Hi ppl I can understand only after I get a perspective to think like this. Now, I have a fundamental question. This looks like a CR. So, in a quantitative section, when/why should there be an approach like a CR question. Why, is jus ok... But, when do we have to approach analytically in a quantitative question. Please clarify.

The table above shows the morning schedule for train X . If Juan took train X on Monday morning, did he arrive at station T on schedule?

Well we are not concerned about the complete schedule but did he arrive at right schedule..... So either statement is sufficient....D _________________

No. We are concerned about his arrival time, not his entire time. Statement 1 just shows that the train traveled at the correct average speed to arrive at Station T, IF, it left station S on time. But we don't know that. It could have left at anytime and still taken 1h02m to arrive but been late.

Think about it; if your flight from NY to Paris takes 8 hours, and is scheduled to arrives in Paris at 13:00 GMT; but arrives at 15:00 GMT due to a 2-hour delay at NYC, would you still say that your flight arrive in Paris ON schedule (even though it took 8 hours, which was the stated flying time)?

To me it seems like the question is asking, did the train travel the distance between the stations in the alotted time of 62 mins.

1. Sufficient because it took him exactly 62 mins.

2. Not sufficient because we don't know which train he took, maybe he took a 7AM train and it got to station S at 8:10.

1 is Not suff. as explained by others before.

2. Is sufficient, because it clearly states that Juan took train X. This is given in the question stem, and is another perfect example of a deceptively simple but deviously tricky question from GMAT makers.

I have found, as I do an ever greater number of both Quant and verbal questions, that it is crucial in GMAT to read the question stem VERY VERY carefully. The devil is in the details.

Again, if you correctly distill this question down, it is not that hard at all (although still not sure if it truly is a 700+ level question).

Hi,

nice question!

Using (1), It mentions only the time of travel taken by Juan. If he started at 7:08 then he would have reached on time. But time of departure is not given. Thus, Insufficient.

Using (2), Juan arrived at office at 8:30 and 20 minutes ago he arrived at station, i.e. at 8:10. So, he arrived on time. Sufficient.

(1) Juan arrived at station T on Monday morning 1 hour and 2 minutes after he left station S .

(2) Juan arrived at his office at 8:30 (EST) on Monday morning, which was 20 minutes after he arrived at station T .

B. From (1) we can not conlude whether the train departed from Station S on schedule.

Old topic that I found , I feel it needs a bit of discussion

We have been able to prove that A is not sufficient , because we cannot assume that the train left Station S on time . Which is very correct , we shouldn't assume anything, right?

For statement B why are we assuming that Train arrived at station T the same Monday morning that it left station S. It is highly impractical but not entirely impossible that due to a calamity the train was stuck in between and it took 7 days to repair the tracks and only then the next Monday morning the train arrived at station S,coincidentally at 8:10 EST.

I think we also shouldn't assume that 8:10 Monday arrival at T is the same Monday morning it left S , it could be the next week Monday morning or even after 2 weeks.

No where in Statement B does it say Juan arrived at T the same Monday morning it left S.

Please tell me why is this scenario not possible at all.

I think there is a small scope for argument that B too is insufficient based on the logic above.

I think C would be more accurate , because if Juan arrived at 8:10 at Station T and it took 1 hour 2 minutes then Train arrived at T the same Monday morning it left S .

I vote for C.

Hope others will agree.

The questions asks: "did he arrive at station T on schedule?" We know that Scheduled Arrival at Station T is at 8:10 (EST). From (2) we get that he arrived at Station T at 8:10 (EST). Thus (2) is sufficient.
