Wait, is the answer C here? I keep thinking each statement alone gives us something but we need both to compare. Let me recheck...

This one tripped me up because of the ranges on both sides. 4 steaks at 6-7 min each is 24-28 min, and guests come in 25-30 min. So there's overlap and we can't be sure. Classic GMAT trap.

Took me way too long and I still second-guessed myself. The 6-7 min per steak combined with the arrival window is sneaky.

Quick tip: whenever you see two ranges in DS, test the extremes. If the bad case still satisfies, sufficient. If it overlaps, usually not.

Common trap

Applying the order of operations out of sequence or rounding intermediate values before the final step.
