(3) How many times would you have to write the number 6 when you write from 1 to 100?

(4) A bus contains 23 men and 14 women. In the first stop after the start, 11 men board and 2 women do. In the next stop, 6 men board and 3 women do. In the next, 2 men alight and 2 women do, but also 2 men board the bus and 2 women do. The question is, how many places did the bust stop from the start to the destination? (You are granted 20 seconds for this, as a special case!)
