Five laundries in rows; columns: washing machines, weekly pounds (thousands), weekly revenue (thousands of dollars), staff. Sortable.
Laundry	Machines	Weekly pounds (000s)	Weekly revenue ($000s)	Staff
Spotless	40	200	320	18
Tidewash	60	348	432	30
Pristine	25	150	300	14
Lumen	50	280	392	24
Sudsy	30	180	252	16

The table shows five commercial laundries: the number of washing machines, weekly laundry processed in thousands of pounds, weekly revenue in thousands of dollars, and the number of staff. The table can be sorted by any column. For each statement, select Yes if it must be true based only on the data shown; otherwise select No.

(1) From the data shown, it can be determined which laundry earns the most revenue per pound: . (2) More than half of the laundries process at least 6,000 pounds per machine each week: . (3) Tidewash's weekly pounds exceed those of Spotless and Sudsy combined: .

Answer & Explanation

Correct answer

1: Yes · 2: No · 3: No

One statement asks only whether a per-pound figure can be determined, one counts a per-machine ratio against a threshold, and one tests a single maximum against a sum of two.

Statement 1 - Yes. The table prints no revenue-per-pound column, but it gives both weekly revenue and pounds, so the ratio is computable: Spotless $1.60, Tidewash $1.24, Pristine $2.00, Lumen $1.40, Sudsy $1.40. The highest is Pristine, the smallest laundry, so the answer can be determined. The statement asks only whether it can be determined, and it can. The trap is to answer No because no such column is shown, or to pick Tidewash for its largest raw revenue; the most revenue is not the most revenue per pound.

Statement 2 - No. Pounds per machine is weekly pounds divided by machines: Spotless 5,000, Tidewash 5,800, Pristine 6,000, Lumen 5,600, Sudsy 6,000. At least 6,000 describes only Pristine and Sudsy, which is two of the five, not more than half. So the statement is false. The bait is to rank by raw pounds, where Tidewash at 348,000 and Lumen at 280,000 look high, even though those large laundries spread their load over many machines.

Statement 3 - No. Tidewash's 348,000 pounds is the single largest count, but Spotless and Sudsy together process 200,000 + 180,000 = 380,000, which is more. So the statement is false. The trap is to assume the single busiest laundry must beat any two others; a lone maximum seldom outweighs the sum of two sizeable rows.

The lesson: a ratio you can compute is determinable, a per-machine figure is built not read, and a single maximum is not a sum of two. Correct answers: Yes / No / No.
