Answer
a). Total Scholarship fund at the end of 10 year = 956,792.65
b). Interest = 356,792.65
Work Step by Step
a). Invest per three month = 15000
Compound interest rate quarterly is 9% = 0.09
Total Scholarship fund at the end of n year = $\frac{P [(1 + \frac{r}{n})^{n\times t} - 1]}{\frac{r}{n}}$
Total Scholarship fund at the end of 10 year = $\frac{15000 [(1 + \frac{0.09}{4})^{4\times 10} - 1]}{\frac{0.09}{4}}$
= 15000$\times$ 63.79
= 956792.65
b). Interest =956792.65 - (15000$\times$4$\times$10) = 956792.65 - 600000 = 356792.65
