Marinada '22

[lang=hr] Cvilidreta nije stigao pretvoriti svu slamu u zlato. U jednoj je smjesi omjer zlata i slame $2:3$, a u drugoj $3:7$. Miješanjem ove dvije smjese želi dobiti $16$ kg zlata i slame u omjeru $5:11$. Koliko kilograma druge smjese Cvilidreta mora uzeti da bi to postigao?

By mixing these two mixtures he wants to get $16$ kg of gold and straw in the ration $5:11$. How many kilograms of the other mix Rumpelstiltskin has to take in order to accomplish what he wishes?
