A) 365/6	B) 73/6	C) 35/6	D) 835/6	E) 200/6
Number of GB that E uses every day: 7/9   Number of GB that F uses every day: 5/4   Number of GB that E and F use every day: 7/9+5/4=73/36   Number of GB that E and F use in 30 days: 30x(73/36)=365/6   Number of GB remaining: 200-365/6=835/6   Answer is 835/6
