Angle 1: 109 A ship with the capacity of cattle and sheep refers to a full platoon of ships under 500 tons. The captain needs to have a Class C certificate of competency, with a professional qualification of at least 48 months and a college degree or above, so it can be inferred that the age of the captain is at least 22 years old +4 years = 26 years old.
Angle 2: First of all, I graduated from school with an average age of 22. I have been a sailor for two years, then I took the third mate for two years, then I took the second mate for two years, then I took the second mate for two years, and then I passed the training and took the first mate for two years. Usually I am 30 years old when I sit on the first mate. It usually takes 10 years for the first mate to arrive at the captain, so it can be inferred that the captain's age is 40 years old.
From the perspective of financial accounting
The cash flow of each cow is 6000 yuan, and the cash flow of each sheep is 1000 yuan. The market value of a ship that can carry so many cattle and sheep is expected to be10.50 billion yuan. Therefore, it can be concluded that the total assets (fixed assets plus inventory, captain's other cash, etc.) are 198400 yuan.
Regardless of inflation, depreciation and other factors, the captain's professional salary is 65,438+10,000 (average annual income), and there will be no cash flow if he is educated 16 years old. So it can be inferred that the captain is now 36 years old.
Starting from the thinking of primary school students
The addition, subtraction, multiplication and division of numbers 75 and 34, only 75 minus 34 equals 4 1, which is between 1 and 100. So most people will think that the age of the captain may be 4 1 year.
