It will give the file called Luton

Read/Write/Execute Permissions for the owner of the file (First 7)
Read/Write/Execute Permissions for members of the group that owns the file (second 7)
and Read and Execute permissions for everyone else (last 5)

It will give the permission suggested by the rowansmith to a file. But if the Luton is a directory then It will give the same permissions to Luton as well as the files and subdirectories which Luton contains.

Read/Write/Execute Permissions for the owner of the file (First 7)
Read/Write/Execute Permissions for members of the group that owns the file (second 7)
and Read and Execute permissions for everyone else (last 5)

4=Read
2=Write
1=Execute

the chmod command changes file / directory permissions. The -R is normally used to set the permissions of sub directories and files within them.

The number 775 is octal presentation of permissions for owner (left most 7), group (middle 7) and others (right most 5)

an octal digit (3 bits) represents the read (left most bit), write (middle bit) and execute / run (right most bit) permissions.

If the bit is set to 1 then the permissions is granted. In your example 775 means:

owner read,write,execute group read,write,execute others read, execute
0
