Thus, whatever time it was, must have ended in 0. Only D works. _________________ Veritas Prep | GMAT Instructor Veritas Prep Reviews Save$100 off any live Veritas Prep GMAT Course

Just look at the last minute digit of both 6:27 and 2,880,717. Both are 7, so when subtracted, the last minute digit will be zero. Only answer D ends on 0.
