Question

Difficulty: EasyCategorical Classification and Sorting

A corporate audit department classifies incoming project files using two criteria: Compliance Category and Funding Level.

Files are prioritized according to the following strict hierarchy:
1. First, by Compliance Category: Category 1 (Urgent Audit) > Category 2 (Standard Audit) > Category 3 (Routine Check).
2. Second, within the same Compliance Category, by Funding Level: High Funding > Low Funding.

Based on these rules, what is the correct sequence of the four project files listed below when sorted from highest processing priority (1st) to lowest processing priority (4th)?

  1. 1File Beta (Category 1, High Funding)
  2. 2File Alpha (Category 1, Low Funding)
  3. 3File Gamma (Category 2, High Funding)
  4. 4File Delta (Category 3, High Funding)

Answer

The correct order from highest to lowest priority is File Beta, File Alpha, File Gamma, and File Delta.
The correct ranking applies the primary criterion (Compliance Category: Category 1 > Category 2 > Category 3) first, which places File Beta and File Alpha in the top two positions, followed by File Gamma in third, and File Delta in fourth. Within Category 1, applying the secondary criterion (Funding Level: High Funding > Low Funding) places File Beta ahead of File Alpha.

Step-by-Step Solution

1
Group the files by the primary precedence criterion (Compliance Category).
Category 1 files (File Beta and File Alpha) have higher priority than Category 2 files (File Gamma), which have higher priority than Category 3 files (File Delta).
Compliance Category is the primary sorting key specified in the rules.
2
Apply the tie-breaker criterion (Funding Level) to files within Category 1.
File Beta (High Funding) ranks ahead of File Alpha (Low Funding).
When Compliance Categories are identical, High Funding takes precedence over Low Funding.
3
Assemble the complete sequence from highest to lowest priority.
1st: File Beta, 2nd: File Alpha, 3rd: File Gamma, 4th: File Delta.
Combining primary category sorting and secondary funding level tie-breaking yields the definitive order.
