A person deposited 1000 yuan in the bank on January 1, 1999, with an annual interest rate of 10%. It is required to calculate: (1) compound interest once a year. The balance of the deposit account on January 1, 2002 is What is the balance of the deposit account on January 1, 2002 If 1000 yuan is deposited into 250 yuan at the beginning of 1999-2001, the interest rate is 10%, and the balance at the beginning of 2002 is calculated by compounding interest every year Suppose you deposit the same amount in four years. How much should you deposit in each period in order to reach the balance of the first question

A person deposited 1000 yuan in the bank on January 1, 1999, with an annual interest rate of 10%. It is required to calculate: (1) compound interest once a year. The balance of the deposit account on January 1, 2002 is What is the balance of the deposit account on January 1, 2002 If 1000 yuan is deposited into 250 yuan at the beginning of 1999-2001, the interest rate is 10%, and the balance at the beginning of 2002 is calculated by compounding interest every year Suppose you deposit the same amount in four years. How much should you deposit in each period in order to reach the balance of the first question

1. Compound interest once a year. The balance of the deposit account on January 1, 2002 is
1000*(1+10%)^3=1331
2. Compound interest every quarter. What is the balance of the deposit account as of January 1, 2002
1000*(1+10%/4)^12=1344.89
3. If 1000 yuan is deposited into 250 yuan at the beginning of 1999-2001 respectively, and the interest rate is 10%, the balance at the beginning of 2002 can be calculated with compound interest every year
250*((1+10%)^3-1)/10%*(1+10%)=910.25
4. Assuming that the same amount is deposited in four years, how much should be deposited in each period in order to reach the balance of the first question
Annual initial deposit: 1210 / ((1 + 10%) ^ 4-1) * 10% / (1 + 10%) = 237.02
Year end deposit: 1210 / ((1 + 10%) ^ 4-1) * 10% = 260.72

If the annual interest rate of the deposit is 3.5% and the compound interest is calculated, how much money can he get back from the bank after five years?

The formula of compound interest calculation is: F = P × (1 + I) n (power) f: final value of compound interest P: principal I: interest rate n: integral multiple of interest rate acquisition time, sum of 5-year principal and interest = 10000 × (1 + 3.5%) ^ 5 = 11876.86 yuan

An enterprise now deposits 1000 yuan into the bank at an annual interest rate of 10%, calculated by compound interest. What is the sum of the principal and interest that can be withdrawn from the bank after four years

1000*（1+0.1）^4=1464.1
