A certain job was completed by three workers. They manufactured machine parts (each machine part was made by one particular worker). The whole task took 15 hours, and the total wages paid to the three of them were $142 000$ forints (HUF, Hungarian currency). The wages were proportional to the quantity of machine pars manufactured. It took the first worker 12 minutes to make one machine component. The second worker got twice as much money as the first worker, and the third one was paid $8 000$ forints less than the second one. How many machine components did each of the three workers make?
