Data Interpretation & Logical Reasoning for CAT

DILR is rated the most unpredictable CAT section because it is not organised by topic the way QA is — it is organised into 4-5 independent sets (a table, a chart, a logic puzzle, a caselet), each carrying 4-6 questions, and no candidate can comfortably finish all of them in 40 minutes. The actual tested skill is triage: spending the first 3-4 minutes surveying every set, fully solving the 2-3 that are genuinely tractable, and abandoning or partially attempting the rest, rather than getting anchored on the first set in booklet order. Data Interpretation sets reward arithmetic fluency (percentages, ratios, weighted averages) applied to tables and charts; Logical Reasoning sets reward systematic diagramming of arrangements, rankings and relations; Games & Tournaments and Caselets are recognisable sub-formats with their own fixed solving templates once you've seen a few of each.
