What are the weights of the five boxes?
A shipping manager wants to determine the weight of five boxes. Each weighs a different integer amount less than 100 kg. Unfortunately, the only scales available measure weights greater than 100 kg. The manager therefore decides to weigh the boxes in pairs so that each box is weighed with every other box. The weights of ten pairs are (in kilograms) 110,112,113,114,115,116,117,118,120, and 121. From this info, the manager can determine the weight of each box. What are the weights of each of the five boxes? .
