It's possible on Monday, Wednesday or Thursday

There are four Sundays in August of one year. What day is the first day of August of this year?

It's Thursday

There are five Sundays and four Mondays in August this year, so August 1 this year is a week ()
A. One B. five C. six D. day

31÷7=4… 3. To ensure that there are five Sundays, four Mondays and the last day must be Sunday, then the remaining three days should be put in the front, that is, Friday, Saturday and Sunday, so August 1 of this year is Friday

(Yangzhou, 2004) there are five Wednesdays in a certain month of a certain year, and the sum of their dates is 80 (take the date as a number, for example, 22 as 22), then the 3rd of this month is week ()
A. Day B.1 C.2 D.4

Let the first Wednesday be the x day. According to the meaning of the question: x + X + 7 + X + 14 + X + 21 + X + 28 = 80, the solution is x = 2, that is, the first Wednesday of this month is the 2nd, so the 3rd is the Thursday
