Answer:
3631
Explanation:
The correct order of the letters is as follows:
A, B, I, N,O,R,W
Number of words begin with A = 6!
Number of words begin with B ~ 61
Number of words begin with I = 6!
Number of words begin with N = 6!
Number of words begin with 0 = 6!
Number of words begin with RAR = 4!
Number of words begin with RA/B = 3!
Now the next word is RAINBOW (it is the first word which begins with RAIN)
So the ranking of the word RAINBOW
=5 x 6!+ 4!+ 3!+1 = 3631
