Anonymous users2024-02-051. Let's take a look at Xiao Ming's words first:
If I don't know, Xiaoqiang definitely doesn't know", then Xiao Ming must know that the n that Xiaoqiang knows will not be in the only two months of days, that is, June 7 and December 2, the only number of days, otherwise if it is in June or December, although he doesn't know the exact date, Xiaoqiang may know. It won't be Xiaoqiang, and I definitely don't know.
Then June and December are naturally excluded. March and September are left.
2. Let's look at Xiaoqiang's words again:
I didn't know about it, but now I know ยป.
Let's start with the days of March and September.
March 4, March 5, March 8.
September 1 September 5.
There are two days on the 5th, and if n is 5, it is impossible for Xiaoqiang to say that he knows m. So the 5th is excluded.
Only remained. March 4 March 8.
September 1st At this time, because there are three dates, the number of days is unique, Xiaoqiang can tell, but we still don't know which day. So the final key is in Xiao Ming.
3, Xiao Ming said that he also knew.
Naturally, it can't be March 4th and March 8th, which are the only days of the 3 days, Xiao Qiang can naturally judge it, but Xiao Ming can't, so March is excluded.
So to sum up, the answer is September 1st.

Anonymous users2024-02-04The first sentence: If the birthday is June 7 and December 2, that is, when n is the only one, Xiaoqiang will know it regardless of the month. So Xiao Ming is sure that Xiao Qiang doesn't know, which means that the month of his birthday is definitely not in these 2 months.
That is, birthdays can only be in March and September, and what Xiao Ming said is absolutely true.
The second game: Because if n is 5, then Xiaoqiang still won't know that month, the problem is that Xiaoqiang knows, so n is 4, 8, 1. i.e. March 4th, March 8th, September 1st.
The third sentence: Now Xiao Ming also knows, if m is 3, then Xiao Ming should still not be able to tell whether it is 4 or 8, so if the answer is September 1, then Xiao Ming's words are true.
So the answer; September 1.
Xiao Ming said: If I don't know, Xiao Qiang definitely doesn't know.
Reflected information: Xiaoqiang's answer will not be the only day, so remove June 7, December 2.
March 4, March 5, March 8.
June 4, September 1, September 5.
December 1 December 8.
Reflected information: You can't know the birthday if you know the month alone, so remove June 4.
March 4, March 5, March 8.
September 1 September 5.
December 1 December 8.
Xiaoqiang said: I didn't know it at first, but now I know.
Reflected information: The correct date is the answer to m (month) can be obtained by knowing only n (day) in the remaining days after the above condition is true).
Xiao Ming said: Oh, then I know too.
Correct answer: March 4.

Anonymous users2024-01-31There is no solution to this problem of yours. The reason is as follows: the empty space in the first row is a, b, and so on:
c, d, e, f, g, h, from the rows as follows: a+b=15, c+d=6, e+f=18, g+h=19; From the columns, we get the following: a+e=10, d+h=24, b+f=25, c+g=10; from above.
1. The comparison of five formulas yields b-e=5, from.
3. Seven formulas give b-e=7. Others are similar. Therefore, there is no solution to this question.
1) Since Xiao Ming, who knows the month, said: "If I don't know, Xiao Qiang definitely doesn't know", which means that the month in his hand is definitely not June and December. Because if it is June or December, Xiaoqiang may have 2 or 7 in his hand, so that Xiaoqiang can directly judge it. >>>More
