Answer:
As the relative position of the vowels and consonants in any arrangement should remain the same as in the word EDUCATION, the vowels can occupy only the before mentioned 4 places and the consonants can occupy 1st, 2nd, 4th, 6th and 9th positions. The 4 vowels can be arranged in the 3rd, 5th, 7th and 8th position in 4!
