question: Mr. Robles buys 315 bananas, which is enough to feed his three monkeys for a week. One monkey eats 10 bananas each day. The second monkey eats 4 more bananas than the first monkey and the third monkey eats the rest of the bananas for the day.  How many bananas does the third monkey eat each day?
answer: Each day, the three monkeys eat a total of 315/7 = <<315/7=45>>45 bananas.
  The second monkey eats 10 + 4 = <<10+4=14>>14 bananas a day.
  So the first and the second monkey eat a total of 10 + 14 = <<10+14=24>>24 bananas each day.
  Hence, the third monkey eats 45 - 24 = <<45-24=21>>21 bananas each day.
