A yacht club conducts a training race every Friday and Sunday during the summer months weather permitting. If the club was able to conduct a race every Friday and Sunday in the month of July, how many races were there that month?
(1) There were five Tuesdays in the month.
(2) The twenty-fifth of July was a Thursday.
Solution:
Month of july has 31 days. A week has 7 days. each "day" gets 4 repeatition (7x4=28) plus 3 days get repeated again one time.
so we can say, 4 days get repeated
