chmod 644 myfile / chmod 644 myfile

chmod 764 myfile / chmod 764 myfile
4.
chmod 754 myfile / chmod 754 myfile
Correct Answer: chmod 754 myfile / chmod 754 myfile
rwx = 4+2+1 = 7, r-x = 4+1 = 5, r-- = 4, so the octal mode is 754. 755 wrongly gives execute to others and 644 removes the owner's execute bit. / rwx=7, r-x=5, r--=4, अतः ऑक्टल मोड 754।
