Table Charts— Concepts, Formulas & Shortcuts
- Read the question first, then extract only the cells you need from the table.
- Percentage change = (new − old)/old × 100 — always divide by the OLD value.
- Convert percentages to fractions to speed up division: 12.5% = 1/8, 16⅔% = 1/6.
- When options are widely spaced, approximate aggressively instead of computing exactly.
- Check the units in the table header — "in hundreds" or "in lakh" is where most careless errors happen.
- For "which is highest" questions, compare ratios directly rather than computing every value.

Table Charts — Frequently Asked Questions
How much time should a DI set take?+
About 4–5 minutes for a five-question set in bank exams. If the first two questions take longer than that, leave the set and return only if time permits.
What is the commonest mistake in table DI?+
Ignoring the unit stated in the table header. A table "in hundreds" turns 50 into 5,000 — and a wrong unit makes an otherwise perfect calculation worthless.
