What difficulty is this problem?

­It should be Medium difficulty.

The answers are directly from the data given. No inference or analysis required except comparing the data on one or two of the tabs.

In q2: it uses the language if it is the number of vehicles passing through the intersection from one specific direction during the current 40-second signals.... doesn't one specific states that the exact number is only from one of the direction? On basis of this, 2000 is the exact same number for two directions, shouldn't this be a no?­

Agree. It was very hard to follow the diagram! Left, right arrows... It delayed me trying to make sense out of the complex illustration...

Bumping Srishti's response, that was my thinking as well and I don't understand why it's incorrect

the wording of the question drove me nuts 
 

What does one specific direction means?
It means from east or from west and so on.

If it were to mean that the number coming from a direction has to be unique, it could be
1) Number of vehicles unique to a specific direction.

chetan2u I'm still not sure based on your explanation. As you said, from one specific direction means from the east, or from the west, etc. Mathematically, or means one, or the other, but not both. Your counter example with the word "unique" uses "specific direction" in your definition, which is the phrase we're trying to define, so it is still unclear.

If I write unique from a direction, it means the number of vehicles coming from a direction must be unique.

My stress was on ‘unique’ and that if it were to mean what earlier posts suggested, word similar to unique would be used.

If I write number of vehicles from a specific direction, specific is adjective referring to direction so it talks of east or west etc.
So, the point on same number of vehicles from a direction not to be considered is not mentioned anywhere.

 

­If we wanted to calculate the percent in 1c, it would be 6.76% am I right chetan2u KarishmaB ?­

Note that we have been given figures for each direction and each turn. For example, look at the lightest grey bar of people coming from Weston. 5000 came straight, 2000 turned right and 2200 turned left. Similarly we have all figures for all other towns too. 

For each of the following quantities, select Yes if it can be deduced from the information provided. Otherwise, select No.

The number of vehicles passing straight through the intersection on Central Highway on a typical weekday morning

Central highway is the vertical one. We have figures for people going from North to South (3000) and South to North (5000). Hence this can be deduced from the give info. 
ANSWER: YES

The current duration in seconds, including gaps, of one full cycle on the stoplight's signals

We do not know the duration of "gaps". Signal times do not include gaps. Note in the second tab "The gaps in time between each step in the pattern are not included in the times given below." Hence we cannot deduce this. 
ANSWER: NO

The percent of the vehicles passing through the intersection on a typical weekday morning that turn left off of Province Highway, from both directions

We have all the values so we can find how many people are turning left off Province highway. So we can simply mark Yes and move on without actually looking for the values (2200 coming from West and 3000 coming from East. We will need to divide this by the total number of vehincles, a calculation which will take time and should not be done)
ANSWER: YES


For each of the following numbers, select Yes if it is the number of vehicles passing through the intersection from one specific direction during the current 40-second signals on a typical weekday morning, according to the information provided.
Otherwise, select No.

40 second signals are at all right turns. 
From East - 1240 turn right. From North - 1000 turn right. From West - 2000 turn right and From South - 2000 turn right

1000 - YES

2000 - YES

3000 - NO
ANSWER


Based on the information provided, what fraction of the number of vehicles on typical weekday mornings, passing through the intersection from Weston, passes through the intersection during the current 20-second-long stoplight signals?

20 sec signals are the left turns from Province. (2200 coming from West)
Also from Weston, 5000 go straight and 2000 go right. 
Hence required fraction =\( \frac{2200}{(2200 + 5000 + 2000)} = \frac{22}{92} = \frac{11}{46}\)

ANSWER: 11/46­

­Yes this question is in the Gmat focus mocks. I encountered it in Mock 2.
