(i) If the shortest side is greater than 100/3, other two sides would also be greater than 100/3, thus proving its perimeter to be more than 100. Hence, YES. It's A/D now.
(ii) Since the longest side is greater than 50 and no side is more than the sum of the other two sides in a triangle, hence the sum of other two sides must also be greater than 50, thus proving its perimeter to be more than 100. Hence, YES.
