    If all the vowels -A E O- are together and all the consonants-C G H N P-are together in COPENHAGEN, what are the number of ways they can be arranged?

    And if the E's are not next to each other?

    Also if Four letters are selected from the 10 letters of the word COPENHAGEN.

    -> Find the number of different selections if the four letters must contain the same number of Esand Ns with at least one of each
