Jorge travels to meet once daily with exactly six clients, Clients A

So here we can try the permutations and combinations on our own to see how the path is formed

We have to always follow the logic :

John schedules each subsequent meeting according to which client is the least distance from the meeting immediately prior to it.

So here first John goes to E

Now from E ,then from E the closest client is A with a distance of 2,so John will go to A,next from the closest point is F with a distance of 1,so John will go to client F,

Now from F,again the closest is A,but he already met A,so the next closest in the list is B with a distance of 4 ,so from F John will go to B

Now from B,the closest is C with a distance of 2,so John will go to C

Now from C,the closest is B,but John has already met B,so he will go to D(at a distance of 3 from C),so John will go to D.

Now from D,John will not go to A,since he already met A.

So the answers are Yes,Yes,No

Hi SajjadAhmad, could you share the official explanation, I am not able to come to Yes for the second one.

thanks.

First E, so we have E-2-3-4-5-6

Check E's row (or column). A is closest.
So we have E-A-3-4-5-6

Check A's row. Ignore E-A.
F is closest. So we have E-A-F-4-5-6

Check F's row. Exclude E-A-F.
B is closest. So we have E-A-F-B-5-6

Check B's row. Exclude E-A-F-B.
C Is closest. So Jorge's full schedule is E-A-F-B-C-D.

Now check the answer choices
Client B then Client C - Yes
Client C then Client D - Yes
Client D then Client A - No

­For part 2, 18 miles is farther away than 12 miles? Therefore it should be D then C, no??

You are going wrong in measuring distances. The distances has to be measured from the last client visited.

So we start with E.
1. Scan for all the distances to the remaining clients from E. Closest is A, 2 km away.
2. From A, scan the distances to the remaining clients less E from A. Closest is F, 1 km away.
3. Now, he is with F and the closest is B, 2 km away.
4. From B, C is 3 km away
5. Finally, D is 3 km from C.

Thus, the clients visited are E-2-A-1-F-4-B-2-C-3-D.
# Client B then Client C - Yes
# Client C then Client D - Yes
# Client D then Client A - No

On a lighter and logical note, B to D is 15 km while B-C-D is just 5 km. Why would someone call B-D as direct route when a route one-third the length is available.

­Most urgent: E

1. Sort by E => A is closest

2. Sort by A => F is closest

3. Sort by F => B is closest (since already met A)

4. Sort by B => C is closest

5. Last is D


1. Client B then Client C => Yes

2. Client C then Client D => Yes

3. Client D then Client A => No

Am I the only one who immediately didnt get that the question wanted me to chart Jorge's path? Its written in such a confusing manner for such an easy question. I thought all the question was asking from me was to check the options in isolation. It got right by fluke but still a wrong approach is a wrong approach.

The wording seems ok. At most, perhaps putting down "on Tuesday" at the end of second sentence would make it clearer but otherwise, I think it works. 

On Tuesday, Jorge’s most urgent meeting will be with Client E. For each of the following pairs of clients, select Yes if Jorge will schedule meetings with the given clients in the given order "on Tuesday." 

Sorry that I'm late to the party, but for whatever it's worth: I completely agree with Karishma here. (Hi, Karishma!)

The wording is sometimes a bit murky by design on DI, but there really aren't many ways to interpret this prompt. We get a full paragraph about Jorge's scheduling. Then we're asked specifically about the order of Jorge's meetings.

But your question is an important one in general, because you're almost certainly going to encounter questions whose language is either unclear or ambiguous, and you'll need a game plan. So here's what we suggest:

Read the prompt twice. Carefully.

If something is still ambiguous, see if you can arrive at a reasonable interpretation. (In this question, you might think, "well, they're asking me specifically about Jorge, so I guess I need to determine the order of his meetings.") If you can, great. You're not going to be certain that your interpretation is the correct one, but that's the nature of the beast. We don't get perfection or certainty in life or on the GMAT DI section.

If after multiple readings, you still have no idea what the question is asking for and can't arrive at any reasonable interpretation, just run away. If you have time to come back and tackle the question again with fresh eyes, great. If not, well, the odds of answering the question correctly aren't great, so your time is better spent elsewhere.

For a whole lot more on potentially ambiguous language and other elements of DI, check out this DI video playlist (filmed live) or this stack of DI videos (NOT filmed live).

I hope that helps!
