1. 16 not a multiple of 6

2. 5*3 15 not a multiple of 6 But when combined x has to be an even number so as to make m divisible by 2. So i think it is c.

hi! has anyone here done the free mock test offered by Expert Global? is the level of difficulty of DI at par with that of the actual GMAT exam?

personally i found the questions much more lengthy and difficult compared to the official mocks and hence want to know how others found it too?

i would highly appreciate some help / guidance on this, thank you! 😊

a-stretch-of-highway-segment-x-has-no-traffic-signals-and-comprises-421714.html

A stretch of highway, Segment X, has no traffic signals and comprises three speed zones: One with a speed limit of 55 miles per hour (mph) followed by a 75-mph zone and a second 55-mph zone. Leslie is at a certain point on Segment X, driving at a speed she will exactly maintain until after she has reached the end of Segment X and has entered the next highway segment. Is she driving faster than 55 mph?

(1) Leslie’s speed is at least 5 mph below the speed limit that currently applies to her.

(2) Leslie will reach the end of Segment X without ever exceeding any speed limits.

What is the difference between 2nd statement and question statement actually? Both says end of the segment. What am I missing out? Can anybody help?

The question statement meant to say end of zone, right?

Just the statement 2 is sufficient to answer the question. Because it we take the boundary value of 55 mph throughout the journey, she can cross the segment without breaking any speed limit means we can definitely tell that Leslie is not driving at 55mph

*Faster than 55mph I mean

What is the difference between 2nd statement and question statement actually? Both says end of the segment. What am I missing out? Can anybody help?

Question statement: Three speed zones within Segment X, 55 - 74 - 55 mph. Leslie is at a certain point but will continue with that speed till the end of segment X.
This itself tells us that Leslie is is in 55 mph zone. If she is travelling within the speed limits, answer is yes.

(1) Leslie’s speed is at least 5 mph below the speed limit that currently applies to her.
She is in 55mph zone, so she is travelling at a speed less than 50 mph.
Sufficient

(2) Leslie will reach the end of Segment X without ever exceeding any speed limits.
We know she is in the last stretch, that is 55 mph zone. So, she never crosses that limit.
Sufficient

I doubt, then statement 2 will not be sufficient.

Great question from GMAC

Question statement: Three speed zones within Segment X, 55 - 74 - 55 mph. Leslie is at a certain point but will continue with that speed till the end of segment X.
So Leslie is in some zone ans she will maintain that speed till end. If she is travelling at 60 mph, she will continue with it till the end of the segment X. If she is travelling at 100 mph or 10 mph, 55 mph zone, she will continue with it till the end of the segment X.

(1) Leslie’s speed is at least 5 mph below the speed limit that currently applies to her.
If she is in 55mph zone, so she is travelling at a speed less than 50 mph.
But if she is in 75 mph zone, she will continue at a speed less than 70 mph, which could be greater than 55 mph.
Insufficient

(2) Leslie will reach the end of Segment X without ever exceeding any speed limits.
We know she has to surely cross the last stretch, that is 55 mph zone. If she was travelling at a speed greater than 55 mph, she would surely cross the third stretch at that speed and thus, cross the speed limit. But, she never crosses that limit. SO, surely she is travelling at a speed that at the most 55 mph.
Sufficient

Hello All,
can anyone help me with the below question:
a-new-line-o ... 24790.html

The weakener implies that if they already had healthy skin then the effect of the new product will not give any substantial and conclusive evidence that it is better.
And for the strengthener, what i feel is (i may be wrong)that since the passage is all about study findings ( third party) and not what author thinks himself/herself, hence the opinion of a qualified judge( also a third party) may be the right thing to consider here

Natural ingredients and affordability is not to be considered here i guess, because if one is considered to be a strengthener then both should be the right answer for strengthener but both are out of context

i understand the weaken statement, but i got confused with option A for the strengthen part. I mean if Glow cosmetic are the only cosmetics out there that provide natural and healthy look then it strengthen the claim they make in the passage about providing a natural and healthy look.

i mean, i am not sure if i am looking at it from a wrong perspective, but i could not understand why not option A

It won’t be option A because the passage says that glow cosmetic provides a more natural and healthy look. Passage has not mentioned that glow cosmetic is the only one that provides natural and healthy look. So others can provide the same but to some less extent
