Question

The number of arrangements that can be made with the letters of the word MEADOWS so that the vowels occupy the even places?

Answer 1

A. 720
B. 144
C. 120
D. 36

Explanation:

The word MEADOWS has 7 letters of which 3 are vowels.

-V-V-V-
As the vowels have to occupy even places, they can be arranged in the 3 even places in 3! i.e., 6 ways. While the consonants can be arranged among themselves in the remaining 4 places in 4! i.e., 24 ways.
Hence the total ways are 24 * 6 = 144.

Correct Answer: 144 ✔
