    Question

    Using all the letters of the word RELIAN, how many words

    start with a vowel but end with a consonant?
    A 216 Correct Answer Incorrect Answer
    B 144 Correct Answer Incorrect Answer
    C 120 Correct Answer Incorrect Answer
    D 192 Correct Answer Incorrect Answer

    Solution

    The word RELIAN has three vowels – E, I, A.
    If a word starts and ends with a vowel:
    3P2 = 3 × 2 = 6
    Remaining 4 letters → 4! = 24
    Total = 6 × 24 = 144

    Now, to count those that start with a vowel but end with a consonant:
    Start: E, I, A → 3 ways
    End: R, L, N → 3 ways
    Middle 4 letters → 4! = 24

    So total = 3 × 3 × 24 = 216
