Subj:.....Conscientious Milkman (S639)           From the book              "More Mathematical Puzzles                 of Sam Loyd"            Edited by Martin Gardner            From: Dover Publications in 1960 Photo from krishnA industrieS   How much pure milk must have been delivered on each of the four streets? It was the daily practice of a conscientious milkman to fill his two sixteen-gallon cans with pure milk before he started out to serve customers on four different streets.  The same number of quarts were delivered on each street. After serving the first street, he connected with the city water supply and, lo, his cans were again filled to the brim! Then he served street number two and again backed up to the fount to replenish his cans as before. He proceeded in this way to serve each street, filling his cans with water after each street had been delivered, until all his happy customers were served. If forty quarts and one pint of pure milk remained in the cans after all his customers were attended to, how much pure milk must have been delivered to each of the four streets?
