Answer / Ravi Kant Kushwaha
Chmod 755 sets file permissions to read, write and execute (rwx) for the owner, read and execute (rx) for group members, and only read (r) for others. The '7' in octal notation represents these permissions for the owner (4+2+1=7), the '5' represents read and execute permissions for group and others combined (4+1=5).
