Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday.
What day comes three days after the day which comes two days after the day which comes immediately after the day which comes two days after Monday?
Work backwards from Monday - Two days after Monday is Wednesday. The day immediately after is Thursday. The day two days after is Saturday, and three days after that, is Tuesday
Add all the days together (3 + 2 + 1 + 2) and then count up from Monday.
