If 6 persons working 8 hours a day earn Rs.8400 per week, then how much will 9 persons be working 6 hours a day each per week:
Answer: Rs.9450

Earnings are proportional to total work hours. For 6 persons, 8 hours/day, 7 days/week, total hours = 6 × 8 × 7 = 336, earning Rs.8400. Rate = 8400 ÷ 336 = Rs.25/hour. For 9 persons, 6 hours/day, 7 days/week, total hours = 9 × 6 × 7 = 378. Earnings = 378 × 25 = Rs.9450. Studying this highlights proportional calculations, providing lessons on workforce earnings planning.
