Quantitative Ability & Data Interpretation for XAT

XAT's single largest section, and documented as leaning harder on arithmetic, geometry and mensuration than CAT's comparatively algebra-heavy style. Arithmetic alone (percentages, ratios, time-work, interest) is the biggest individual topic, rewarding memorised shortcuts — alligation, the successive-percentage-change formula, the CI−SI difference trick — over full derivation under no-calculator time pressure. Geometry and Mensuration is nearly as large and almost entirely direct formula application once Pythagorean triples and the similarity area-ratio-squared rule are automatic. Algebra is comparatively light, Modern Math (permutations, probability, progressions, sets) rewards fast sub-type identification, and Data Interpretation tests arithmetic economy on tables and charts more than reading difficulty.
