Table Data Interpretation
Reading a rows-by-columns table fast: row totals versus column totals, per-unit figures, growth between columns, ratios across rows, and rounding to the options.
What you will be able to do
- Tell a row total from a column total and compute whichever the question needs.
- Derive per-unit figures by dividing one column by another.
- Find growth between two columns using the earlier column as the base.
- Round table figures sensibly when the options are far apart.

How a table set is laid out
A table DI set has one axis running down the rows (branches, products, cities, people) and another running across the columns (years, months, categories). Every cell is one absolute figure unless the title says otherwise.
The questions ask you to combine cells: down a column, across a row, or one cell against another. Nothing is hidden, but a wide table makes it easy to read the wrong line, so keep a finger or a pointer on the row you are working.
