  1. Laryngitis, a Greek orator, was born on July 4, 30 BC and died on July 4, 30 AD.                   How old was he when he died?

  2. "But I don’t have time for school," explained David to the truant officer. "I sleep 8 hours a day, which adds up to 122 days a year, assuming each day had 24 hours in it. There is not school on Saturday or Sunday, which amounts to 104 days a year. We have 60 days for summer vacation. I need 3 hours a day for meals – that is more than 45 days a year. And I need at least 2 hours a day for recreation – which comes to over 30 days a year. If you add these figures up you’ll see they come to 361 days. You see," continued David," that leaves me with only 4 days to be sick in bed, and I haven’t even taken into account the 7 days that we get for school holidays each year."

    The truant officer scratched his head. "Something is wrong here", he mumbled. But try as he could, he was unable to find any thing inaccurate about David’s figures. Can you explain what is wrong?
