Let's break PERMUTATIONS into its vowels and consonants -
Vowels - {P,R,M,TT,N,S}
Consonants - {E,U,I,O,A}
So we have six different vowels and 5 different consonants.
Also, we have two consonant which are similar.
Case 1 : The two consonants selected are different
Number of ways of choosing a vowel (middle alphabet of the word) = 5 C 1 = 5
Number of ways of choosing a consonant = 6 P 2 = 30
Total ways = 30 * 5 = 150 ways
Case 2 : The two consonants selected are same
Number of ways of choosing a vowel (middle alphabet of the word) = 5 C 1 = 5
Number of ways of choosing a consonant = 1 (Two Ts)
Total ways = 1 * 5 = 5 ways
Total ways = 150 + 5 = 155 ways
IMO - B

Does "that the vowel always been in middle?" mean anything? I guess it doesn't really matter to solve the question
