Question

"Einstein riddle" The riddle asked us to complete a table of answers in a way that ensured various constraints were satisfied. A "correct" answer to the riddle was a completed table that satisfied all the constraints provided. The table was 5 rows by 5 columns. For each row you could pick the order of 5 parameters - for example, the order of 5 different colours or 5 different car models. In this particular problem there were no duplicate assignments - i.e. you couldn't have two cars of the same colour or make.

How would allowing duplication on the colour of the cars affected the problem ?

Answer 1

If you allow duplication on the colour of the cars, then you should left one or more cars.
