(1) Mary moved out on June 24.
Clearly insufficient as it does not tell how many portions of 360 were for utilities.

(2) The amount Mary paid for utilities was less than 1/5 the amount Mary paid for rent.
Insufficient as it does not tell when did Mary move out.

Combining statements 1 and 2
Let rent be x so utilities will be less than x/5.
x + x/5 = 360

Hence, utilities will be 60 for the whole month. For 6 days to refund it will be less than 12$ we don't exactly what less than 12$.

Therefore, the correct answer is E
