Hello,
Can you please assist with this? This is from MGMAT:
It takes Amy between 6 and 7 minutes to grill a steak, and she can only grill one steak at a time. She does not need to take breaks between steaks. Can Amy finish grilling all the steaks needed for her party before her guests arrive?
(1) Amy needs to grill four steaks for her party.
(2) Amy's guests will arrive in 25 to 30 minutes.
Sorry, I don't have the OA. I thought it should be E

The following cases satisfy both statements.gmattesttaker2 wrote:Hello,

(1) Amy needs to grill four steaks for her party.
(2) Amy's guests will arrive in 25 to 30 minutes.
Worst-case scenario: GREATEST possible time per steak + EARLIEST possible arrival time.
Greatest possible time for 4 steaks = 7*4 = 28 minutes.
Earliest possible arrival time = 25 minutes.
In this case, the steaks are not grilled on time.
Best-case scenario: LEAST possible time per steak + LATEST possible arrival time.
Least possible time for 4 steaks = 6*4 = 24 minutes.
Latest possible arrival time = 30 minutes.
In this case, the steaks are grilled on time.
Thus, the two statements combined are INSUFFICIENT.
The correct answer is E.
