Question for Practice Questions Level 3: Quadratic Equations & Linear Equations
Try yourself:Three drunkards agreed to pool their vodka and decided to share it with the fourth drunkard (who had no vodka) at a price equal to 5 roubles a litre. The first drunkard contributed 1 litre more than the second and the second contributed 1 litre more than the third. Then, all four of them divided the vodka equally and drank it. The fourth drunkard paid money, which was divided in the ratio of each drunkard's contribution towards his portion. It was found that the first drunkard got twice as much money as the second. How much money did the second drunkard get (in roubles)?
