Core methods · Analytical Ability

For data sufficiency, test statement I alone, statement II alone, then both together. A statement is sufficient only when it determines one unique answer. For series, compare consecutive differences before testing ratios or alternating patterns. In graph questions, record units and distinguish percentage change from percentage share.

Worked example

Is x positive? I: x² = 9. II: x > 2. Statement I permits x = 3 or −3, so it is insufficient. Statement II guarantees x is positive and is sufficient by itself.
