Civil Service Clerical Ability Practice exam

In the word "INVOLUNTARILY," we can analyze the letters to identify which ones appear more than once. The letters present in the word and their frequencies are as follows:

- I appears 2 times.

- N appears 2 times.

- V appears 1 time.

- O appears 1 time.

- L appears 2 times.

- U appears 1 time.

- T appears 1 time.

- A appears 1 time.

- R appears 1 time.

- Y appears 1 time.

From this count, the letters I, N, and L are the only ones that occur more than once. Each of these letters is repeated, which confirms their contribution to the total count of letters that appear more than once in the word.

Since there are three letters (I, N, and L) that occur more than once, the correct answer reflects this accounting and thus indicates that the total number of distinct letters used more than once is three. This understanding is essential in determining the frequency of letters in a word for similar questions on tests assessing clerical abilities.
