GMAT Quantitative Section have inequality questions mostly appearing in data sufficiency type of questions. Moreover, these questions are deep concepts based wherein unless GMAT exam takers understand those concepts in detail , it is very difficult to choose the right answer. Also techniques like random substitution of values to check the sufficiency of statements generally make candidates fall into the answer traps which GMAT exam makers intend you to fall into. Hence it is highly recommended to do understand concepts through right content or with the help of **expert GMAT tutor/instructor**. Also most of the time there comes a question based on inequality and modulus combined. Hence understanding the modulus concepts, tricks to solve modulus inequality questions are very useful. For instance if there is modulus inequality like , I2x+3I<5 then the best way to solve it is to firstly copy the entire inequality as it is assuming that there is no mod which means it becomes 2x+3 <5 which further simplifying gives 2x <2 and then x<1. This is one solution and now to get second solution we need to copy the left side of inequality as it is and then changing the sign of inequality and changing the sign of number on the right. Which becomes 2x+3>-5 which then becomes 2x>-8 and then x>-4. Hence the combined solution of the two solutions obtained is -4 <x <1.

This technique is very useful to solve most of the modulus inequality where either there is mod on one side of inequality or two sides of inequality. Similar to this there are many other techniques to solve modulus inequality questions at GMAT quickly and easily which can be learned thorough right content or taking help from expert GMAT tutor/instructor.
