Question

A.
11
B.
23
C.
35
D.
12

Answer 1

To determine how many more pages per minute printer B can print than printer A, we first need to calculate the printing speed of each printer in pages per minute.

For Printer A:

• Pages printed: 576 pages
• Time taken: 48 minutes

Printing speed of Printer A: \[ \text{Speed of Printer A} = \frac{576 \text{ pages}}{48 \text{ minutes}} = 12 \text{ pages per minute} \]

For Printer B:

• Pages printed: 1,104 pages
• Time taken: 48 minutes

Printing speed of Printer B: \[ \text{Speed of Printer B} = \frac{1,104 \text{ pages}}{48 \text{ minutes}} = 23 \text{ pages per minute} \]

Now, we can find the difference in printing speeds between Printer B and Printer A: \[ \text{Difference} = \text{Speed of Printer B} - \text{Speed of Printer A} = 23 \text{ pages per minute} - 12 \text{ pages per minute} = 11 \text{ pages per minute} \]

Thus, Printer B can print 11 more pages per minute than Printer A.

The answer is: A. 11
