    ....... 2 bonds. therefore x and y is the amount in each. x + y = 1500... 8 percent per annum, so 1.08x is left after a year, 10 percent per annum so 1.10y is left after a year. 132 was earned therefore. x+y = 1500 1.08x + 1.1y = 1500+132. solve the system of equations.

    oh. 8% GAIN so you already have 100% because that is the full value, so after a year it is 108%, do you see why?
