1) the first letter must be Y you fix the first space as Y. remaining 4 spaces can be filled in 4*3*2*1 ways = 4!

3 consonants , 2 vowels you can choose first letter from 3 consonants in : 3 ways after that, you can choose second letter from 2 VOWELS in : 2 ways after that, you can choose third letter from remaining 2 consonants in : 2 ways after that, you can choose fourth letter from remaining 1 VOWELS in : 1 ways finally, you can choose third letter from remaining 1 consonants in : 1 ways so total possible ways = 3*2*2*1*1 = 12
