Solving 33. [Problem Solving 2] * Four students on an excursion came across an old weighing machine and decided to weigh themselves. "Sorry," said the owner, "that machine is only accurate for weights over 220 lb." "That's OK," replied one student, "we will hop on two at a time." The results of the pairings in pounds were: 225, 230, 232, 233, 235 and 240. What was the weight of the lightest student? 111 lb o 1 2 3 456789 x Whrte 3.1 @ Copyright.
