How many words ca

Answer :

In ORDINATE,


The vowels are O,I,A,E.



As vowel can occupy the odd places only, in the above diagram vowels will occupy 1st,3rd,5th,7th places only.


Now 1st place can be filled in 4 ways.


3rd will be in 3 ways.


5th will be in 2 ways.


7th will be in 1 way.


Rest of the words will be filled in even places in 4! Ways.


So total ways = 4× 3× 2× 1× 4!


= 4× 3× 2× 1× 4× 3× 2× 1


= 24× 24


= 576


Hence there are 576 ways.
