It goes without saying that the toughest GMAT Quant Problems are GMAT Data Sufficiency questions involving Inequalities. One specific issue that arises when solving tougher questions of this type is how to combine the two statements when both involve inequalities. Let us use two GMAT Data Sufficiency questions to understand how to go about combining inequalities.
Sometimes the process of teaching helps the teacher as much as the student. I was in Hyderabad the last weekend, conducting a GMAT Boot Camp for IMS Hyderabad students and during the course of the session, I discovered a better way to solve an old problem. Towards the end of a long and grueling day of solving 700-800 level problems we came to this Data Sufficiency problem as part of the segment where we focus specifically on the toughest type of Data Sufficiency problems – those involving inequalities.
In the previous Quantitative post , we saw how seemingly tough and time-consuming Data Sufficiency problems usually require a certain amount of pre-work. In most cases if the pre-work is done properly, you will precisely know what information is required to answer the question even before you go to the statements. The GMAT question below is another one of such problems.
