The octal number for these permissions is 755.
Here's the breakdown of the permissions:
Owner (user): Read (4), Write (2), Execute (1) → 4 + 2 + 1 = 7.
Group: Read (4), Execute (1) → 4 + 1 = 5.
Others: Read (4), Execute (1) → 4 + 1 = 5.

Group: Read (4), Execute (1) → 4 + 1 = 5.

Read = 4 Write = 2 Execute = 1
Files are assigned in User, group, other
7 = all permission to the user.
5 = Read Execute to group.
5 = Read Execute to group.
So, the answer = 755.
Files are assigned in User, group, other
7 = all permission to the user.
5 = Read Execute to group.
5 = Read Execute to group.
So, the answer = 755.

The order is user, group other where each consists of a triplet in the form rwxrwxrwx.
Now we use 1 to grant a permission and 0 to remove a permission.
For all permission to user substitute 111 for the first triplet = 7.
For read and execute to group substitute 101 for the second triplet = 5.
For read and execute to others substitute 101 for the third triplet = 5.
Ultimately its 755.

Read = 4.
Write = 2.
Execute = 1.
User = read,execute ( 4+1) = 5.
Group = read,execute ( 4+1) = 5.
User = read,write and execute ( 4+2+1) = 7.
Than answer is 755.
Write = 2.
Execute = 1.
User = read,execute ( 4+1) = 5.
Group = read,execute ( 4+1) = 5.
User = read,write and execute ( 4+2+1) = 7.
Than answer is 755.

RWX is the sequence for read write and execute.
R = 100 (binary form) = 4.
W = 010 = 2.
X = 001 = 1.
=> read+write+execute = 111 = 7 (binary to decimal conv.)
And, read+execute = 101 = 5.
R = 100 (binary form) = 4.
W = 010 = 2.
X = 001 = 1.
=> read+write+execute = 111 = 7 (binary to decimal conv.)
And, read+execute = 101 = 5.

User = read,write and execute ( 4+2+1) = 7.
Answer = 755.

Execute = 1.
