To make the non-technical background new joiners understand the process of manufacturing colour TVs better, LG has hired the services of Due North Inc. consultants. Due North is a consultancy firm which provides technical training of all the household equipment to the non-tech background new joiners at LG. To facilitate the training process, it has been decided that there will be six groups of new joiners namely A, B, C, D, E and F and each of the groups is scheduled at least once a week. All the groups will start their training on the same day and will also end their training on the same day.

(i) Sunday is a holiday.

(v) E group is scheduled everyday, but not on Thursday and Saturday.
(vi) A group is scheduled on alternate days.
(vii) C group does not meet on Monday and Tuesday
(viii) A and D groups never meet on the same days.
(ix) D group is scheduled only once a week on either Wednesday or Friday.
