A table chart arranges data in rows and columns. Read the heading and units first, then locate only the cells a question needs.
1Approach
Note the unit (thousands, lakhs, crores) before computing
Row totals and column totals answer most 'highest/lowest' questions
Percentage change = (new − old)/old × 100; 'X is what % of Y' = X/Y × 100
2Speed tips
Approximate when options are far apart
Compare ratios by cross-multiplying instead of dividing
Average = total ÷ count; you rarely need every value
