The rescued turtle invited Taro to Ryugu Castle. At Ryugu Castle, Otohime showed us a chorus of Thai flounder and a dance of a herd of sardines. However, Thai and flatfish were hungry and ate sardines. Thailand ate eight sardines and four flounders each, and the number of sardines was just 70% of the initial number. Otohime-sama, who was watching it, said, "If Thailand eats 15 sardines and 3 flounders, the number of remaining sardines is 1500 or more and 2000 or less." How many sardines, ties, and flounders were there?
