Statement 1: This statement does not give enough information. We know there are 6 colors, but we don't know how many albums, it might be 56 albums, so there are definitely no same colors in the same album. On the other hand, there might be 6 albums, and he decides to put all the same color in one album.
So, statement 1 is not sufficient.
Statement 2: This statement does not give enough information. We don't know how many different colors there are. Maybe there are 56 different colors, maybe there is only one color.
So, statement 2 is not sufficient.
Both statements together: If we know there are 6 different colors, the only way that an album does not have two or more of the same color of stamps is, is that there are at most 6 stamps in each album, each one from a different color. Since there are 56 stamps and \( 56=9*6+2 \), we can confirm that 9 albums are not enough for all the stamps to be divided as 6 stamps per album. So there is at least one album with two or more of the same color.
So both statements together are sufficient.

Bob is organizing his stamp collection by placing all 56 of his stamps into several albums. Is there at least one album that contains two or more stamps of the same color?
(1) Each stamp in the collection is exactly one of the following six colors: red, blue, green, yellow, orange, or violet.
(2) Bob places the stamps into 9 albums, with each stamp placed in exactly one album.
Y/N Question
56 stamps to organise.
statement 1 => 6 colors => could be 9 sets of 6 diff collors and 2 stamps extra. However we don't know how in wich percentage every color would be present among the stamps, nor how many albums will be used to organize the stamps => NS
Statement 2 => 9 albums will be used , but it is not indicated in what capacity and how many collors there are => NS
1 & 2 combined => In the best case, if the colors would be evenly present and If he would place 1 set of 6 different colors in every albums, he would still have to add the 2 stamps left to place in one or two of the albums. If one color would be more present or if he would place more than 6 stamps in one album, one album should contain two or more stamps of the same color.
=> sufficient
Answer is C

Given Statements:
Each stamp is exactly one of the following six colors: red, blue, green, yellow, orange, or violet.
Bob places the stamps into 9 albums, with each stamp placed in exactly one album.
Statement (1):
Each stamp is exactly one of the following six colors: red, blue, green, yellow, orange, or violet.
No information about how stamps are distributed..Alone not sufficient
Statement (2):
Bob places the stamps into 9 albums, with each stamp placed in exactly one album
No info about the colors of stamps. They could all be unique (different colors), or all same...Alone not sufficient
Combined:
If we have 9 albums, and each album holds the maximum number of unique colors (6 stamps, one of each color), then the total number of stamps that can be distributed without any color repetition in any album is:
9 albums * 6 stamps/album (each of a different color) = 54 stamps.
However, Bob has 56 stamps.So remaining 2 must repeat within the same album
Together sufficient Option C
