    Answer: All mammals are warm-blooded; cats are mammals; therefore cats are warm-blooded

  3. A bank processes 240 transactions per hour. How many transactions does it process in 45 minutes?

    Answer: 180

    240 transactions/hour × (45/60) hours = 180 transactions.

  4. If 'neither A nor B' is true, which statement follows?
