Read a table or chart, then compute ratios, growth and shares.
Tables & Charts: the essentials
- Before any arithmetic, note the units, whether a totals row is given, and whether the question wants a row (one item across periods) or a column (one period across items).
- Percentage growth = (later − earlier) ÷ earlier × 100. The base is the earlier value, so a small base can beat a larger absolute rise.
- Share = part ÷ total × 100. A share can peak in a different year from the absolute figure.
- Pie charts: 1% = 3.6°, so a sector's angle = percentage × 3.6, and its value = angle ÷ 360 × total.
- A ratio of two percentages needs no conversion to money: the total cancels.
- Average = sum ÷ number of entries; when every row has the same count, compare totals instead.
- On bar and line charts, read the scale first: an axis that does not start at zero exaggerates change.
Approximation
- When the options are far apart, round to two or three significant figures.
- Build percentages from blocks: 17% of 460 = 46 + 23 + 9.2 = 78.2 (10% + 5% + 2%).
- Use fraction equivalents: 12.5% = 1/8, 16⅔% = 1/6, 33⅓% = 1/3.
- Compare fractions by cross-multiplying instead of dividing.
- x% of y = y% of x: 18% of 50 is 50% of 18, which is 9.
Example: sales rising from 400 to 500 grew by 100/400 = 25%; falling back to 400 is a 20% drop.
