Question

If all the permutations of the letters of the word chalk are written in a dictionary the rank of this word will be

Answer 1

Answer:

The rank of the word CHALK is 32

Step-by-step explanation:

The word is

CHALK

No. of letters in the word = 5

Total permutations = $5!$ = 120

If the first letter is A then total permutations = $4!$ = 24

If the first letter is C and second letter A then total permutations = $3!$ = 6

If the first letter is C and second letter is H then in dictionary order the third letter will be A and fourth will be K

i.e. the 24 + 6 + 1 = 31st letter will be CHAKL and the 32nd letter will be CHALK

Therefore, the rank of the word CHALK will be 32

Hope this helps.
