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.   Akhilesh ? answered Mar 20 '25 at 21:00
