Puzzle Trio 21

61. The 9th November 1999 had an unusual feature.
If it was written in the form 9/11/99 then it could be seen that 9 x 11 = 99
Or, in words: day × month = year (Last two digits)
When was the next time that would happen?

62. Using the same digit three times, the
number 24 can be made in different ways.
One of the ways is 8 + 8 + 8
Find two other ways of using
three digits (all the same) to make 24

63. The diagram shows a map of all the roads in Squaresville.
Judy lives at A and works at B and likes finding a different route every time she has to go to work.
(She always takes the most direct route going home!)
Naturally, she always choses a road and a direction which takes her nearer to (and not away from) her work.
How many different ways can she find of getting to work?
