Housing Allocation and Exceptions Summary

Core framework

Resource distribution under scarcity
Queues form when demand exceeds supply
Priority scoring ranks applicants
Exceptions modify standard rules

Scoring structure

Base score from condition, income, size, time
Exception points for special cases
Final score determines queue position

System design principles

Balance efficiency with equity
Formal approval with documentation
Oversight through audits and transparency
Abuse prevention through verification

Key insight:

Exceptions prevent rigid systems from creating unjust outcomes, but must be carefully managed to maintain system integrity and public trust.

Resource Allocation and Queue Prioritization: Solved Questions with Step-by-Step Explanations (2 Problems)

Question 1 · Decision Making (DM) MCQ

Context: A housing committee uses a priority scoring system for 4 applicants: A (Base 80), B (Base 70), C (Base 60), D (Base 50).

There are two types of exceptions:

Type X: +20 points. Eligible if Base Score < 70.
Type Y: +30 points. Eligible if Base Score < 60.

Rules:

Exceptions are allocated in order of Base Score (highest first).
There is exactly 1 slot for Type X and 1 slot for Type Y.
An applicant can claim only one exception.
Tie-breaker: If final scores are equal, the applicant who claimed the exception with the higher point value gets priority. If the exception values are the same, the one with the higher base score wins.

Applicant B realizes that by intentionally reducing their base score to 69 (e.g., by resigning and rejoining), they would become eligible for Type Y instead of Type X.

If B successfully games the system by reducing their base score to 69, what will be the final allocation order (from highest priority to lowest)?

A.
C, B, A, D
B.
B, A, C, D
C.
B, C, A, D
D.
A, B, C, D

Correct Answer:

Step-by-Step Solution

Key idea: This is a system gaming question recognisable by the eligibility thresholds and the incentive to manipulate base scores.

Step 1: Determine the new base scores. A=80, B=69 (gamed), C=60, D=50.

Step 2: Allocate exceptions in order of base score.

A (80): Not eligible for X (<70) or Y (<60). Score = 80.
B (69): Eligible for X (<70) and Y (<60). Since exceptions are allocated highest base first, B picks first. B will pick Y (+30) because it's higher. Score = 69 + 30 = 99.
C (60): Eligible for X and Y. Y is taken by B. C gets X (+20). Score = 60 + 20 = 80.
D (50): Both taken. Score = 50.

Step 3: Rank the final scores.

B: 99
A: 80
C: 80
D: 50

Step 4: Resolve the tie between A and C. Both have 80. A has no exception (value 0). C has Type X (value 20). C wins the tie-break.

Final Order: B, C, A, D.

Wait, let me re-evaluate the tie-breaker rule. "the applicant who claimed the exception with the higher point value gets priority". A claimed NO exception. C claimed X (+20). So C wins.

Order: B, C, A, D.

Let me check the options. Option C is "B, C, A, D".

Wait, in my thought process I said Option B is "B, A, C, D". Let me fix the solution to match the correct option.

If B=99, C=80, A=80. C wins tie over A. So B, C, A, D.

Let me adjust the options in the YAML to make "B, C, A, D" the correct answer.

Answer: C

Question 2 · Decision Making (DM) MCQ

Context: A company has a strict First-In-First-Out (FIFO) housing queue. Employee E is 50th in the queue. The CEO wants to move E to the top to reward exceptional performance. The Union strongly opposes this, citing the FIFO policy.

The HR head proposes a compromise: "E must voluntarily negotiate with the 49 employees ahead in the queue to reach a consensus on a non-monetary swap or compensation. HR will only formalize the exception if a unanimous consensus is reached."

Assertion (A): This consensus-based approach is the most appropriate Decision Making action because it balances the CEO's desire to reward E with the Union's demand for fairness, without violating the core FIFO policy.

Reason (R): By making the exception contingent on voluntary consensus, the system preserves FIFO as the default rule, ensures no financial precedent is set, and distributes the cost of the exception among the willing stakeholders.

Options:

A) Both A and R are true and R is the correct explanation of A.

B) Both A and R are true but R is not the correct explanation of A.

C) A is true but R is false.

D) A is false but R is true.

A.
Both A and R are true and R is the correct explanation of A.
B.
Both A and R are true but R is not the correct explanation of A.
C.
A is true but R is false.
D.
A is false but R is true.

Correct Answer:

Step-by-Step Solution

Key idea: This is a stakeholder management question recognisable by the conflict between a top-down directive (CEO) and a structural rule (Union/FIFO).

Step 1: Evaluate Assertion (A). The consensus approach satisfies the CEO (E can still move up if consensus is reached), satisfies the Union (FIFO is not arbitrarily broken, and no one is forced to move), and maintains fairness (stakeholders have agency). Thus, A is true.

Step 2: Evaluate Reason (R). The reason correctly identifies the mechanism: voluntary consensus shifts the burden from the system to the individuals. It preserves FIFO as the default, avoids setting a monetary precedent (which could lead to future demands), and ensures that those displaced are compensated in a way they find acceptable. Thus, R is true.

Step 3: Check the link. R directly explains WHY A is the most appropriate action. The mechanism described in R is exactly what makes the approach in A successful and policy-compliant.

Answer: A
