possible ways and these words are written
out as in a dictionary, what is the rank of the
word ?rachit?.
(a) 485
(b) 480
(c) 478
(d) 481
Answer Posted / jitendra singh
the maximum possible combinations for the name rachit is:
6!=720 (as there are no repeated words)
now for r to start in dictionary we have to go through
a,c,h and i so..
a+4 other cominations of words = 5 cominations =120
similarly for c,h,and i
total=120+120+120+120=480 + first word that is rachit... hence answer is 481
