Therefore, it is important for students to become comfortable with the pattern of the common questions asked as well as keeping composure for tackling the odd knotty one.

The instructions for solving the Data Interpretation question are of utmost importance as they contain crucial direction and information on what it wants you to find out.

Prioritize accuracy and read the whole question once before solving the question. 

• Be Familiar with the Symbols and Units

The standard units like a meter per square, centimeter, seconds, minutes, hours, etc may change the whole nature of the question. Especially with data interpretation, question-setters like to play with units in order to confuse students. Get comfortable with common symbols, units, conversion measures, and formulae and practice as much as you can.

• Use Different Techniques to find Answers!

Solving answers through reverse answering or elimination methods is an important tool in your arsenal. When you come across a seemingly difficult or unprecedented Data Interpretation question, you use such techniques to get the correct answer. The majority of the quantitative aptitude questions in all significant national competitive tests revolve upon data interpretation. In government exams like SSC, Bank, RRB, Insurance exams, etc., there are usually 10 to 15 questions based on data interpretation.
