Hook:
Imagine you are a detective, and the numbers in front of you are your clues. A table of marks, a bar graph of rainfall, a pie chart of expenses — each one hides a story, and your job is to uncover it. In exams like SSC, Railway, and Banking, data interpretation questions work exactly the same way: the answer is always sitting inside the data; you only need to read it correctly and calculate smartly. Master this skill, and you will find that DI questions are some of the quickest marks you can earn.
