Hmm, problem with understanding the possible values

Where was I wrong ? From the given information in 1) and 2)I thought both cases are possible

q = 1150 p = 1101 => 1,06q > p

but its also possible that

q = 1150 p =2000 => 1,06q < p and therefore answer 5 should be the right one

Given that q - p < 50 , it can be possible that p > q, right ? and q - p <0

Hi sapuna,

We're told that that a computer can be bought at a store for $P + 6% tax or bought from a catalog for $Q total. We're asked which price is bigger. This is essentially a YES/NO question....

Which is bigger, 1.06P or Q?

Fact 1: Q - P < 50

We can TEST Values:
Q = 50
P = 1
Q is bigger than 1.06P

Q = 1
P = 50
1.06P is bigger than Q
Fact 1 is INSUFFICIENT

Fact 2: Q = 1150

There's no information about P, so there's no way to know if Q or 1.06P is bigger.
Fact 2 is INSUFFICIENT

Combined, we know...
Q - P < 50
Q = 1150

This gives us.... 1150 - P < 50

1100 < P

Since P > 1100, 1.06P is > 1166
Q = 1150
We now have proof that 1.06P is ALWAYS greater than Q.
Combined, SUFFICIENT.

Final Answer: C

Hi sapuna,

Everyone makes some silly mistakes at some point in their training. You can laugh about it now, but burn these memories into your brain. Too many silly mistakes will kill you on Test Day. Just a handful of silly mistakes, especially at the wrong point in a section, can throw your score off enough to keep you from 700+. Become militant about this process - lots of notes, proper organization, NO silly mistakes - and you'll hit your goal.

To be honest the test I hit yesteday was exactly 700 with 3 super silly mistakes in Q - I calculated taht 6.4= 20 lol , that and 1 else. My exam is on Wednesday. I need 610 + but anything below 650 won`t be that cool. My goal is 700 +

Hi Sapuna,

If silly mistakes are hurting your score, then it's important that you identify and CATEGORIZE these mistakes so that, during tests, you can easily spot situations in which you're prone to making errors. I write about this and other strategies in the following article for BTG: https://www.beatthegmat.com/mba/2012/09/ ... n-the-gmat

Cheers,
Brent

Thank you for the advice. My errors are like..meh. For example on average atm in the q section I have 45 + score with 6-7 mistakes. OUt of the them 3-4 are because of hard problems but the rest are silly - I either didn`t see something or made some stupid calculation. For example the test I just did - the first question was a exponent problem and I kept getting the answer 24 when there is no such answer. I checked I typed it wrong...cuz in the numerator the actual value was 8^2 but I typed it as 8^3 lol . It took me 4 minutes to get it right haha. This could be bad on test day because I can panic that I wont have enough time

Fair enough. Just be sure to watch for some commonalities in your errors. There may be a common thread that will allow you to spot potential error-prone situations in the future.
