GMAT Process of Elimination - Data RangeWhat worries GMAT test takers in Problem Solving is the lengthy calculations, and translation of statements to equations. Lot of students prefers the use of calculators. If you have started solving a few GMAT PS questions, you might have realized that solving some of the toughest GMAT 800 questions does not require even solving them in a traditional manner. Process of Elimination is an often-neglected technique when it comes to solving time consuming and tricky GMAT Problem solving questions.

In this article, we will cover how to classify answer choices into groups, and guess the probable range of the answer based on the facts provided in the question.

GMAT Data Sufficiency Process of EliminationOnce GMAT test takers have learned about the fundamental concepts tested in the exam, focus should be on saving time for each question. In GMAT, each question should be answered in just under two minutes. Data sufficiency follows a format where a question is followed by two statements, labeled as (1) and (2), and five answer choices in the format:

a) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.

b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

c) BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.

d) EACH statement ALONE is sufficient to answer the question asked.

e) Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

Process of Elimination techniques will allow you to complete the GMAT DS questions in less than one and half minutes.

Let us consider a few scenarios:

Statement 1 is insufficient:
