Try searching relevant forums: if-a-b-c-and-d-are-integers-and-ab2c3d4-0-which-of-the-136450.html

If a, b, c, and d are integers and \(ab^2c^3d^4 > 0\), which of the following must be positive?

I. \(a^2cd\)
II. \(bc^4d\)
III. \(a^3c^3d^2\)

A) I only
B) II only
C) III only
D) I and III
E) I, II, and III

Since given that \(a*b^2*c^3*d^4 > 0\), then we know that none of the unknowns is zero. Therefore, \(b^2>0\) and \(d^4>0\), which means that we can safely reduce by them to get \(a*c^3>0\) (so, the given expression does not depend on the value of \(b\) or \(d\): they can be positive as well as negative).

Next, \(a*c^3>0\) means that \(a\) and \(c\) must have the same sign: they are either both positive or both negative.

Evaluate each option:

I. \(a^2cd\). Since \(d\) can positive as well as negative then this option is not necessarily positive.

II. \(bc^4d\). Since \(d\) can positive as well as negative then this option is not necessarily positive.

III. \(a^3c^3d^2\). Since \(a*c^3>0\), then \(a^3*c^3>0\) and as \(d^2>0\), then their product, \((a^3*c^3)*d^2\) must be positive too.

Answer: C.

Hey everyone,

Have been struggling with DI time management. I know all the generic tips across the internet. I am aiming for a 675+ score and will be taking the exam soon. If there’s anyone out there who had scored or even outscored my target, I’d really appreciate it if you could reach out and talk!

Thanks.

Hey!Took the GMAT today and I thought I was doing super good in quants that I thought I’d get Q90 because the questions were super easy . I don’t know how did I ended up getting Q76.
Verbal was brutal and I thought my score will tank in it but V82.
DI was the worst of all with D72. I don’t even know what did I do there.

I have used up all my strategies and honestly I don’t know what else to prepare. Was preparing from Expert’s Global and GMAT Club tests but I don’t know which approach to use anymore. I plan to take the exam again as soon as possible (preferably within 2 months). Any help would be appreciated!

A. 793
B. 795

Also for this question, can someone point to any resource on the method used where they take the difference and solve that way, or if they could explain it would be great
