Puzzle Trio 21
||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?
||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
||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?
