John weighs twice as much as Susan. Susan's weight is 60% of Sam's weight. Mark weighs 50% of Lynn's weight. Lynn weighs 190% of John's weight. Which of these 5 people weighs the least?
This question requires no algebra, just a parsing of the text.

John weighs twice as much as Susan. Self explanatory.
Susan's weight is 60% of Sam's weight. This means Sam weighs more than Susan, but less than John, because Susan is 50%
