急！！求助2道数学狗！！！

（1）是31，如果中文意思对的话

（2）的话，就一个一个试，是最快的方法，有可能是唯一有效的。25的平方是625，35的平方是一千多，45的平方是两千多。所以条件（1）可以确定此数是35

I think the original question may be this

" WHAT IS the minimum number of people that born in JUNE.?"

條件是：出生在六月的人數是 十二個月份裡最多的

總數 356 人

356/ 12= 29 余 四

所以 剩下的四個人有幾種分法

1 1 1 1

1 2 1

2 2

1 3

怎樣才能保證六月的人數是最多的呢？ 29+3=32

anyone????????

No.

WHAT IS the minimum number of people that born in JUNE?
Answer: 0

WHAT IS the minimum number of people that born in JUNE to make the number of people born in JUNE the greatest among all 12 months?

31

LS:

ie:  according to you...... here June won't be the month that has the most people in which they were born.

J    F   M   A  M   J   Ju  A    S  O   N  D
29 29 29 29 29 31 29 29 29 29 29 31= 352  

( option of the remainder 4 can be split to  1 1 1 1 , 2 2  and 1 3)

BUT...

J    F   M   A  M   J   Ju  A    S  O   N  D
29 29 29 29 29 32 29 29 29 29 29 30= 352  

This satisfy the condition that June has the greatest number of people in which they were born.

LS, according to your logic, I can put 175 in January alone and leave 177 in June.

To get the smallest possible number in June, one should try to put the number EVENLY among other months, not try to create some extra hurdles (such as creating a month with 31 people).

then can you please explain??
i am totally lost

This is similar to voting in an election or gambling in Las Vegas: Stick to the same strategy ALL the time.

If you first spread 29 people evenly among 12 month, you should spread the extra 4 people EVENLY among the months AGAIN. Plain and simple. What you get is a few months with 30 people. Then the smallest possible number for June to become the most popular month is 31, just one extra than the rest.

Remember, your goal is to find the LOWEST possible number for June to win the contest.  So do not pile up extra people in any month other than June.  Spread them out!
