The bank issued a two-year Treasury bond with an annual interest rate of 2.55%. Aunt sun bought the bond and received a total of 6306 yuan of principal and interest when it was due. How many treasury bonds did aunt sun buy

Suppose you buy a yuan, because the annual interest rate is 2.55%, so the annual interest is a * 0.0255
The interest for two years is (a * 0.0255) * 2
6000+（A*0.0255）*2 = 6306
(A*0.0255）*2 = 306
A * 0.0255 = 153
A = 153/0.0255
A = 6000
So it's supposed to be 6000
