There are some really cool articles on inequalities in the MBA Library and here is the URL to the same.https://www.beatthegmat.com/mba/category ... equalities
.I, personally, suggest you to frame questions yourself and solve them. For example, if you want to work on Inequality + Mod, frame a question like this |x-4|-6<0 and then solve for x.
|x-4|-6<0
|x-4|<6
-6<(x-4)<6
-2<x<10 is the solution
Here is another example,
|x-4|-6>0
|x-4|>6
x-4<-6 or x-4>6
x<-2 or x >10 is the solution
I also suggest you to make the best use of our friend: Google
. Let me know if you any further help.
