Six identical independent looms take 10 hours for an order, so three take 5 hours.
Ten identical independent painters finish one wall in 6 hours, so twelve take 5 hours.✓Correct answer
A fixed 96 kilometre route takes 3 hours at 32 kilometres per hour, so it takes 2 hours at 48 kilometres per hour.✓Correct answer
Eight identical independent scanners take 9 minutes for a batch, so twelve take 13.5 minutes.
Explanation
For the fixed wall, 10 painters taking 6 hours means 60 painter-hours, so 12 painters take 5 hours; covering the fixed 96 kilometres at 48 kilometres per hour takes 2 hours. The loom claim is the closest trap because halving the number of identical looms doubles the time rather than halving it.
