If first letter is A = 5!/2! = 60 so first letter is A
second letter is O = 4!/2! = 12 it is less than 20 rank is reduced to 20-12=8
now second letter is P = 4!/2! = 12 so second letter is P
now third letter is O = 3!/2! = 3 is less than 8 rank is reduced to 8-3=5
now third letter is R = 3! = 6 so third letter is R
now fourth letter is O = 2!/1! = 2 is less than 5 rank is reduces to 5-2=3
now fourth letter is R = 2!/1! = 2 is less than 3 rank is reduces to 3-2=1
now fourth letter is T = 2!/1! = 2 so fourth letter is T
now Fifth letter is O = 1 so fifth letter is O
n Sixth letter is R
hence Answer = APRTOR

AAO = 4! / 2! = 12
AAPO = 3!/2! = 3
AAPRO = 2! = 2
AAPRR = 2! = 2
= 19
Therefore, 20th word is AAPRTOR
