- Provide a challenging problem that tests both conceptual understanding and practical implementation.
1. Eligibility – From First Principles
1.1 Defining the Eligibility Predicate
Let
- (A(x)) = Age of candidate (x) (in years)
- (E(x)) = Highest completed educational level of (x)
- (E(x) \in { \text{≤10th}, 12^{th}, \dots})
- (D(x)) = Domicile of (x) (state/UT)
- (N(x)) = Nationality of (x)
- (C(x)) = Special category flag (SC/ST/OBC/General)
The eligibility predicate ( \mathcal{E}(x) ) is defined as:
[ \mathcal{E}(x) \iff \underbrace{\bigl(A(x) \ge 16\bigr)}{\text{Age limit}} ;\land; \underbrace{\bigl(E(x) \ge 10^{\text{th}}\bigr)}{\text{Education}} ;\land; \underbrace{\bigl(D(x) \in \text{India}\bigr)}{\text{Domicile}} ;\land; \underbrace{\bigl(N(x) = \text{Indian}\bigr)}{\text{Nationality}} ]
