Hi there!
Here's the answer:
•°•°•°•°•°<><><<><>><><>°•°•°•°•°
COMBINE - A 7 letter word
Out of the 7 places, the Odd places are 1, 3, 5, 7
Vowels in the given word = O, I & E
No. of Vowel in the given word = 3
Remaining letters are C, M, B, N
These 3 Vowels are rock occupy any three of these 4 places.
This can be done in 4P3 = 24 ways
Now,
The remaining 4 places( 3 even and 1 odd place) are to be occupied by 4 consonants which can be done in 4P4 = 4! = 24 ways
Total No. of words = 24 × 24 = 576
