NEW question from GMAT® Official Guide 2019
(DS08420)
For the month of June, Rent & Utilities of $360 is paid by Mary to Omar. A refund is
given because Mary does not stay for the entire month.
(1) Mary moved out on June 24.
This shows that she was not occupying the house for 6 days in the month of June.
However, this information is not enough to find the exact amount of the refund
(Insufficient)(2) The amount Mary paid for utilities was less than 1/5 the amount Mary paid for rent.
We know that the amount Mary paid for utilities was LESS than \(\frac{1}{5}\)th the amount she
paid for rent. However, since we aren't given by exactly how much the cost of utilities is
less than the cost for the rent, we can't find the exact amount of the refund.
(Insufficient)Even with the combination statement, we cannot clearly assess the exact refund which
was returned to Mary(since we aren't given an exact ratio of cost of utilities to rent
(Insufficient - Option E)
