I would have pick y as a percentage OF the total distance. the "OF the total distance" part is ANOTHER smart number (i.e. 100 miles). That would mean I have picked 2 smart number in a single questions.
I then get confused about picking smart number that might give me false/incorrect information.
Can you maybe help me understand where I am missing the point here? Or further elaborate what you have explained below?
As near as I can tell, the only place where you appear to be missing the point is where you said you could choose option A *or* option B and then concluded that this meant you would pick two smart numbers. If you picked one of those options *or* the other, you would end up only picking one smart number. In most cases, you should stick to one smart number, so it sounds like you had the right idea here as long as you took your own advice and implemented only one of those options. :)
Let us know if you have further questions. I'm not convinced I fully addressed your concerns, but it was a little tough to figure out exactly what your real question was.
Hi Tim,
thanks for your prompt reply. Sorry I wasn't clearer with my question as I am trying to get my head around it.
You mentioned that for either option, I am actually only picking 1 smart number. Here's what I was thinking, kindly bear with me...
For this particular question (OG13-PS162), the MGMAT explanation says I can either pick a smart number for the actual Total Distance *or* for y (percentage of total distance)
For option A: I am sure I am only choosing 1 smart number (y=100 for Total Distance)
For option B: It seems like I am choosing 2 smart numbers. Allow me to explain.
For option B (pick y
as a percentage OF the total distance): say I am picking
y (1st smart number) as 20%, then I am picking
Total Distance (2nd smart number) as 100 miles. Which makes y=20miles. But if the 2nd smart number is 120miles, then y=24miles.
This issues came to me as I was looking thru the explanation on the NAVIGATOR and it says "We can choose a smart number for y, if y=40, then in the first leg of the trip, Tom traveled 40%
of 100 miles". Where did this 100 miles come from? Isn' this another smart number?
I hope my question isn't confusing you.
Thanks again.
