1 PRNAUK  
2 PRKANU  
3 PRKAUN  
4 PRNAKU  

Ans.

(3)

We have, A, K, N, P, R, U

Now, to calculate rank

Number of words start with A               = 5! = 120

Number of words starts with K             = 5! = 120

Number of words starts with N             = 5! = 120

Number of words starts with PA           = 4! =   24

Number of words starts with PK           = 4! =   24

Number of words starts with PN           = 4! =   24

Number of words starts with PRA         = 3! =     6

Number of words starts with PRKANU = 1

Number of words starts with PRKAUN = 1

                                                  Total = 440

∴  440th words is PRKAUN.
