To compare net profit per device, we'll need some information about cost per device and revenue per device.

Statement 1 gives us information about cost, but without information about revenue, we can't determine net profit. Insufficient.

Statement 2 gives us revenue information, but without cost information, we can't determine net profit. Insufficient.

When combined, we have the information we need to determine the percent difference in net profit for each device. You could easily plug in numbers to double check, but if you understand what information you need, you can solve conceptually.
