Restating intial rule

What is a product code?

What is a product code?

@yuetngan, Great question. Yes, unless otherwise stated, all of the initial rules are present throughout the entire game. I would recommend diagramming the rules once for each game. Diagramming them for each question wastes precious time and is not advisable. There are some games where there is a rule substitution question at the end where one or more of the rules is swapped out for another rule. In these cases, it can be helpful to write the new rule next to the question to help you make sure you understand it. Regarding what a product code is, a product code is a unique identifier, assigned to each finished/manufactured productwhich is ready, to be marketed or for sale. A product code may also refer to: Universal Product Code, common barcode used to identify packaged products. Even if we don't know what a product code is, we can still answer this question just fine. Don't concern yourself too much with understanding what certain types of things are. Just make sure that you can diagram what you're supposed to. For the purposes of this game, a product code is just a series of five digits ranging from 0 to 4. That's really all we need to know, and that's given to us in the initial rules. Does this make sense? Let us know if you have any more questions!

Hi, what do they mean by respectively?

Both A and E are right... right? How do I continue with this question?

By "respectively," they're referring to the order. Any of the following pairs could be the third and fourth digits, respectively... (A) says "0, 1" Third and fourth respectively means 0 and 1, so it's to let you know that 0 would be in the third spot and 1 would be in the 4th spot. (A) and (E) are not both right. Let's take a look at them. We know an employee generates a series of 5-digit codes. The digits used can be 0, 1, 2, 3, or 4. Each digit is used exactly once. The 2nd digit is double the 1st digit's value The 3rd digit is less than the 5th digit. 1 2 _ _ _ 2 4 _ _ _ The first and second digits have to be either 1 and 2 or 2 an 4 because those are the only two pairs of numbers are double/half of each other, which allows us to satisfy the rule about the 2nd and 1st digits. Using our rules, we can solve for all possibilities of this game. There are 6 possibilities for the game: 1 2 3 0 4 1 2 0 3 4 1 2 0 4 3 2 4 1 0 3 2 4 0 1 3 2 4 0 3 1 With (A), we have 0 and 1. We see that this can be a possibility (2 4 0 1 3), so (A) is out. With (E), we do not see any board with 3 and 4 in the 3rd and 4th positions, so this isn't possible. Thus, (E) is the correct answer choice. Hope this helps. Let us know if you have any more questions!
