n = 12
T repeats = 2 times,
(i) the word starts with P and ends with *
(P ......... (5)
Total words = 9!/2! = 9 × 8 × 7 × 6 × 5 × 4 × 3 = 1,81,440 ways
(ii) Vowels are together: vowels = E,U,A,I,O = * together
∴ they form 1 group remaining +7/8 letters
∴ Total words = 8!/2! = 8 × 7 × 6 × 5 × 4 × 3 = 20,160 ways.
