How many words can one form by shuffling the letters of the word QUEUE, if Q is always followed by U? The words thus formed need not necessarily have any meaning.

Question

Accepted Answer

$12$

Explanation: The word QUEUE has letters: Q, U, E, U, E. Since Q must always be followed by U, treat QU as a single block. The remaining letters are U, E, E. We now arrange 4 objects: {QU, U, E, E}. Since the two E's are identical, the number of arrangements = 4!/2! = 24/2 = 12. Therefore, 12 words can be formed, making Option 4 the correct answer.
