Solution



Given
In this question, we are given that
    • All the letters of “CFOSU” are arranged in dictionary order

To find
We need to determine
    • The rank of the word “FOCUS”

Approach and Working out
If all the letters are arranged in alphabetical order, then we will have words starting with C first, then F, then O, then S, and finally U.

If C is the first word, then the remaining words can arrange themselves in 4! = 24 ways

Next, we will have words starting with F.
    • Words starting with FC = 3! = 6
    • Words starting with FOC: FOCSU and FOCUS

Hence, the rank of the word FOCUS = 24 + 6 + 1 + 1 = 32

Thus, option D is the correct answer.

Correct Answer: Option D
