You are given 5 bales of hay. Two bales are weighed at a time, which equal the following weights:
Thanks! Hi Ivy, I am assuming that these weights are in pounds. Suppose that the bales are labeled a,b,c,d,e from lightest to heaviest. The ten pairs of bales are;
ab,
ac,
ad,
ae Notice that each bale appears four times in the list above and thus the sum 110+112+113+114+115+116+117+118+120+121=1156
adds each bale four times. Hence the total weight of the five bales is 1156/4 = 289 pounds. Can you now find the weights of the other four bales?
Cheers,
