Timed Quant Practice - Medium Section 1 Sample #4.1

[FutureM7Student]

Hi,

The answer states that it should be “27” but Greg’s explanation in the video is “It cannot be determined”

which one is the correct asnwer?

For this question, 27 is the correct answer. The video solution features an outdated version of the question that omits the “a>0” part. Therefore, in that version, “it cannot be determined” is the correct answer.
