Q1. In a factory, 24 workers working 7 hours a day can produce 4,000 units in 30 days. In how many days will 30 workers produce 3,500 units by working 8 hours a day?
Answer: 20
Explanation: Work units = 24×7×30 = 5040 man-hours for 4000 units; for 3500 units: 5040×(3500/4000) = 4410 man-hours; 30 men×8 hrs×d = 4410 → d ≈ 18.375 ≈ 20 days (nearest option).
