Data Sufficiency: Trick or Treat?

Data sufficiency questions are often misinterpreted by most of the aspirants and students. The meaning of Data Sufficiency questions is just the same as the literal meaning of the word “Sufficiency” i.e.  an adequate amount of something, especially of something essential.

So, these questions are need not to be solved rather the candidate is required to identify which option satisfy the given statement of the question.

The Basic Mantra:

  • Attempt the questions with “Option Narrowing Technique”
  • This technique means that try to apply each of the options one by one in the Statements given in the question and check whether it suffices the statement or not
  • This will help you in approaching the question with a target, else you will end up solving the question and waste a lot of time
  • Please understand that you are not required to solve a question You just need to find out which conditions are sufficient to get the answer.
  • Always remember that the basic trick in these questions is the language of the questions, so do take care of even the importance of the punctuations used in the statements as they may infer the meaning altogether
  • Understand the pattern of the Data Sufficiency question thoroughly before attempting them
  • The data sufficiency options say:
  • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
  • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
  • BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
  • EACH statement ALONE is sufficient to answer the question asked.
  • Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed
  • Carefully observe that each of the option in itself has two meanings, for say the first statement says that Statement 1 alone is sufficient and at the same time it also saying that statement 2 alone is not sufficient. So, if you select this option, you must check both the conditions are valid in the question or not and then proceed
  • Same goes with all the remaining statements
  • So, the main catch in Data Sufficiency questions is the language of the questions. Understanding can be improved with a lot of practice.
