The number of arrangements that can be made with the letters of the word PETER so that the vowels occupy the even places?
Choose one:	A) 14	B) 18	C) 12	D) 15	E) 11
The word PETER has 5 letters of which 2 are vowels.   -V-V-V-   As the vowels have to occupy even places, they can be arranged in the 2 even places in 2! i.e., 2 ways. While the consonants can be arranged among themselves in the remaining 3 places in 3! i.e., 6 ways.   Hence the total ways are 6 * 2 = 18.   Answer:18
