One published group count. No fabricated context mix.
The ADA publishes 10 Applied Mathematics (Word) Problems within the 40-question Quantitative Reasoning section.
It does not divide those 10 questions into rate, percent, mixture, work, motion, finance, geometry, or measurement quotas. Those labels organize DAT TRAIN instruction; they do not predict ADA frequency, wording, order, difficulty, or scoring.
Original practice contexts
Eight settings. One modeling grammar.
Every setting begins with the requested quantity, relationship, units, and feasibility conditions—not a keyword-to-operation shortcut.

02Percent

OFFICIAL HIERARCHY → STUDY SEQUENCE
One branch. Two passes.
Inspect the model-translation and result-audit outcomes, their evidence limits, common traps, representations, and source trail before beginning.

Objective 1QR-APP-WRD-01
Translate the situation into a model
Name the requested quantity, define variables, align units, and translate rates, percentages, mixtures, motion, work, finance, or measurement constraints into equations.
Must know
A unit ledger exposes missing conversions and distinguishes a rate from a quantity. The model should state what each variable measures before numbers are substituted.
Evidence limit
The official label is broad; DAT TRAIN examples may organize common contexts but do not claim unpublished ADA context quotas.
Common trap
The operation can be chosen from the numbers alone. The relationships and units determine the model before arithmetic begins.

Objective 2QR-APP-WRD-02
Solve, estimate, and audit the result
Solve an applied model, use the digital calculator selectively, and reject results that fail magnitude, unit, sign, domain, or context checks.
Must know
An estimate predicts the answer’s sign and scale before exact arithmetic. A calculated value must be interpreted in the requested unit and feasible context.
Evidence limit
Calculator output is arithmetic evidence, not proof that the chosen model or interpretation is valid.
Common trap
A calculator display is automatically the answer. Round, label, and test the result against the original situation.

ANSWER INTEGRITY
Relationships choose operations. Units expose mistakes.
01Target
Name the requested quantity, unit, and feasible range.
02Model
Translate the invariant relationship before substituting values.
03Convert
Use factors equal to one until only the requested unit remains.
04Audit
Test the exact result against estimate, scale, sign, and context.
