The Agricultural Bank of China donated 20,000 yuan. How much will it cost in one lump sum after two years?
If you borrow 20,000 yuan and pay it off in one lump sum after two years, according to the current annual interest rate of 5.25%, the loan interest is equal to the loan principal multiplied by the loan time multiplied by the loan interest rate equal to 20,000× 2, and then multiplied by 5% point 25 = 2 100 yuan, which means that 22 100 yuan is paid off in one lump sum.
