Two travelers, one with 64 barrels of wine, other with 20 barrels of wine. They don't have enough money to pay duty for the same. First traveler pays 40 francs and gives his 5 barrels, Second traveler gives his 2 barrels but gets 40 francs in exchange. What's value of each barrel, and duty for each barrel?

• Second Traveler: Cost of 2 barrels=40 francs=> 1 barrel=20 francs.
  First Traveler: pays 40 francs and 5 barrels=40+(5*20)=140 francs.
  therefore value of each barrel is 20 francs and duty is 140 francs

• Assuming both barrels costs the same, if 2 barrels cost 40 francs, each barrel cost 20 francs. Hence duty = 40francs+ 5barrels cost= 40+ 5(20)=140 francs.
