1.784 per day for ten thousand years is .48 yuan, and the annualized rate of return for seven days = principal * interest rate *7/365. If the annualized rate of return for seven days of a monetary fund is 1.782% and the principal is 1 yuan, it can be calculated that the annualized rate of return for seven days is: 1 yuan *1.782%*7/365=3.417 yuan per day.
