A batch of wood, if processed into a school table, can be processed into 100 pieces, and if processed into a school stool, can be processed into 150 pieces. If it is processed into a school table and a school stool at the same time, how many sets can be processed? (One set = one learning desk + one learning stool)
一批木料，如果加工成学桌可以加工100张，如果加工成学凳，可以加工150张．如果同时加工成学桌和学凳，可以加工多少套？(一套=一张学桌+一张学凳)
