As we learnt in 

Rank of any Word -

We arrange the words according to dictionary.

Eq. for SUNIL 

      Rank is 95

- wherein

    I\rightarrow4!=24

    L\rightarrow4!=24

    N\rightarrow4!=24

    SI\rightarrow3!=6

    SL\rightarrow3!=6

    SN\rightarrow3!=6

    SUI\rightarrow2!=2

    SUL\rightarrow2!=2

SUNIL =1=\frac{1}{95}

                                  

 

 50th word of 'AGAIN'

Starting with A-                     A-> 4!=24

Starting with G-                     G-> 4!/2! =12

Starting with I-                     A-> 4!/2!   =12

Starting with N  NAAGI and then NAAIG is 50th word
