Concept: The question tests on the basics of Counting
PRECISION has 9 letters containing 5 consonants (P R C S N) and 4 vowels (E I I O), I being repeated twice
Since we have a restriction that vowels have to occupy even places, we need to satisfy the condition.
The 4 vowels can occupy the 4 even spaces (2nd, 4th, 6th and 8th places) in 4! / 2! = 12 ways
The 5 consonants can occupy the odd places in 5! = 120 ways
Total number of ways = 120 * 12 = 1440 (Option d)
