Answer 2

Answer:

If all the letters of the word SKILLFULNESS are arranged in alphabetical order, the position of three letters remains unchanged.

Explanation:

The given word is SKILLFULNESS.

To arrange the letters in alphabetical order, we sort every letter of the word. The new word obtained after arranging the letters is EFIKLLLNSSSU.

Comparing the position of letters in the two words:

• First position: S and E
• Second position: K and F
• Third position: I and I
• Fourth position: L and K
• Fifth position: L and L
• Sixth position: F and L
• Seventh position: U and L
• Eighth position: L and N
• Ninth position: N and S
• Tenth position: E and S
• Eleventh position: S and S
• Twelfth position: S and U

There are three letters whose position remains unchanged after the arrangement. These are I in the third position, L in the fifth position, and S in the eleventh position.

Therefore, the position of three letters remains unchanged.
