Ask for a logic question, give everyone a logic question

1. The correct answer is that it must be true. Because the employees received the dedication award, the turnover exceeded 5 million, and if it exceeded 5 million, it exceeded 8 million. Because 7 of the 10 chain stores have more than 8 million, and the other 3 are less than 5 million.

Employees with an annual turnover of more than 8 million are entitled to an annual excess award. Therefore, the employee who receives the dedication award must have received the annual excess award. ii Not necessarily true, although the annual turnover of more than 8 million employees can get the annual excess award, but the annual turnover of the annual excess award may not exceed 8 million, even if it exceeds 8 million, more than 5 million may not get the annual dedication award, because the annual turnover of more than 5 million is only a necessary condition for obtaining the dedication award, not a sufficient condition.

iii is not necessarily true. Seven of the 10 chain stores of Senda Group have an annual turnover of more than 8 million, so the vast majority of employees of the chain stores can receive the annual excess award, but it does not mean that the vast majority of the employees of the Senda Group can receive the annual excess award. Because it is likely that the vast majority of chain stores have employees who are only a minority of the entire group.

First of all, whether or not to judge for the current year, if so.

1. Employees who have won the dedication award will receive a certain annual excess award.

2. Those who have won the annual excess award must be awarded the dedication award.

These two are correct, obviously, more than 8 million must be more than 5 million, because the company did not say that it could not have both, so it won two awards.

3. Most of the employees of Vantone Group have won the annual excess bonus--- mistakenly.

Because there are no employees, it is possible that the number of employees in those 3 branches exceeds the number of people in those 7 companies, so it is wrong.

If it is not for the current year's question, there is only a second pair.

It is clear that both the first and the second are correct.

Because: among the ten branches, three are below 500 and seven are above 800, so seven of them are more than 800, and because they can get annual excess awards above 800, the first one is correct in the hypothesis.

The second one is also correct, needless to say.

The third one is less logically rigorous, because three branches under 500 can indeed have more people than seven over 800. So don't pick it.

But according to common sense, three also works, hehe.

Like wolves, sheep, cabbage, or whatever.

Programming should do the trick.

Why are that old man and old lady so bad... = =

This reasoning is wrong because the first "masses" are collective concepts, while the second "masses" are class concepts.

Set Concepts and Non-Set Concepts (Class Concepts) Set Concepts: Concepts that reflect a collection of individual things.

The aggregate is an indivisible organic whole. A property that aggregates have, but individual things don't.

Non-set concepts: Concepts that reflect a class of things. The properties that a class concept has, individual things must have.

The answer is useful, please click Adopt.

Option B: Let A be admitted as P and B as Q, then.

1、p→¬q

2、¬q→p

3. The truth value table of column p is as follows:

By comparison, we can see that there is only one true when p is false and q is false.

The situation of two falsehoods occurred, so neither A nor B was admitted.

First of all, look at CC, it meets the condition of 1. Also in line with 2. But there are two falsehoods so excluded.

Actually, we can find out. 1 and 2 are actually about the same.

b Non-conformity3, non-compliance2, non-compliance 1 exclusion.

d same as b excluded.

A meets 3, but does not meet 1, 2 so two false and one true. Choose A

Option A first assumes that 1 is true and false is obtained from 1 [if A (admitted, the same below), then it is not B] [if B, then it is not A] from 2 [if it is not B, then it is not A] [if A, then B] from 3 [not A] From 2 and 3 it can be seen that if A, both B and not B Contradictory Therefore, the assumption is not true Then assume that 2 is true and false Obtained from 1 [if A, then B] [If not B, then not A] [If not B], then not A] [If not A], then B] from 3 [not A] Obtained from 1 and 2 If it is not B, then neither A nor A Contradictory The hypothesis is not true It can be known that 3 is true and false (the next is very simple, so I will not repeat it) and reason to get A and B choose A
