On one particularly prosperous day, the box was found to contain exactly 100 tokens, with the total amount of gold reaching 15,250 coins. Like a mission to maximize the loot, determine the highest possible number of 500-gold-coin tokens that the donation box could have contained.If x−2y+4z=6x - 2y + 4z = 6x−2y+4z=6, 3x+y+5z=43x + y + 5z = 43x+y+5z=4 and 2x−y+3z=42x - y + 3z = 42x−y+3z=4, then what is the value of (2x–3y+5z)(2x – 3y + 5z)(2x–3y+5z)?75 people are stranded on an island, and they have sufficient food for 100 days. After 10 days, two-third of the people separate from the group in search of a way out. After another 16 days, 25 people return. From this day on, how many days will the food last?
