Rosalie's little brother Connor was born on May 11, 1997,which was Mother's Day. Mother's Day is the second Sunday of May every year.
By the time he is 80, how many times will Connor's birthday have been on Mother's Day?

I solved it!!!!!!!
It will happen 13 times in his whole miserable life
we found the pattern of adding 6 then 11 then 6 then 5 then 6 then 11 then 6 then 5 then 6 and so on tothe original year that he was born in.

sorry, I got it wrong!!!!
I thought he would be breathing as long as 85 years,but he will only breath for 80 years.
well, 12 then!!!
12 is the answer
hoping it's correct,

As we know,there are 365 or 366 days every year.
365/7=52...1, 366/7=52...2
It means 2 days earlier each 4 years
Then the circle is 28 years,he has 4 chances
80/28=2...24
And there 4 chances also at his last 24 years
Totaly 12

蝌蚪文害死人耶. 作者: zxwy 时间: 2008-11-12 08:24
thanks guys,but is there any other way to solve it instead of counting every year?
btw,the answer is 12. 作者: echooooo 时间: 2008-11-12 08:50
Counting every year is just to check and confirm.
Fortunately,the year 2000 has also 366 days.
