Answer:
Required to find the number of words with or without meaning that can
be made using all the letters of the word AGAIN.
In Alphabetical order, the letters of the word AGAIN are A, A, G, I , N.
There are 4 distinct letters with one letter repeating twice.
Hence total number of words will be 5!/2! = 60.
Words starting with A : 4! = 24
Words Starting with G: 4!/2! = 12
Words starting with I : 4!/2! = 12
Already there are (24 + 12 + 12) so the second next word would be the
50 th word.
Next word starts with NAAGI whose rank is 49
and then comes in the dictionary order is NAAIG whose rank is 50
