Question 2
Four musketeers together bought a plot of rectangular shape and paid for it equally. They divided the plot by two cuts into four pieces of rectangular shape, from which every musketeer got one. It turned out that one musketeer obtained as much land as the other three in total. Prove that the price per acre of one musketeer's piece turned out as large as the sum of the prices per acre of the other three musketeers' pieces. (Juniors.)
