If 9 workers can build a wall in 12 days, how many days will 6 workers take to build the same wall, assuming they work at the same rate?
18
Total work = workers × days = \(9 \times 12 = 108\) worker-days.
With 6 workers, days required = \(\frac{108}{6} = 18\) days.
Hence, 6 workers will take 18 days to build the same wall.
