In how many ways can the letters of the word ‘MOMENT’ be arranged?

The correct answer is Option (3) → 360

MOMENT has 6 letters, but M comes twice. Swapping the two M's gives the same word, so each arrangement is counted twice in \(6!\) and we divide by \(2!\).

• Number of arrangements \(=\displaystyle\frac{6!}{2!}=\frac{720}{2}=360\)
