There are 6 letters and 2 vowels in word MONDAY.

Therefore, the right most position can be filled by any of these 2 vowels in 2 ways.

Remaining 5 places of the word  can be filled using any of rest 5 letters of the word MONDAY.

Hence, the required number of words formed using 5 letters at a time   =^5P_5

                                                                                            =5!

                                                                                             =5\times 4\times 3\times 2\times 1

                                                                                             =120

Words formed starting from vowel using 6 letters =2\times 120=240
