Correct answer is: 180
Explanation: Let the total number of employees be $T$
- 40% of $T$ are matriculates: $0.4T$
- Remaining employees: $60\%$ of $T$ = $0.6T$
- 50% of these remaining employees are graduates: $0.5 \times 0.6T = 0.3T$
- The remaining 50% are post-graduates: $0.3T = 180$
- Solving for $T$ : $0.3T = 180$ → $T = 600$
- Therefore, the number of graduates is $0.3 \times 600 = 180$

OPTION a (360): Incorrect, as it does not match the calculated number of graduates.

OPTION b (240): Incorrect, as it does not match the calculated number of graduates.

OPTION c (180): Correct, as it matches the calculated number of graduates.

OPTION d (300): Incorrect, as it does not match the calculated number of graduates.
