Alice deposited $10,000 in her savings account in 2013 at 2X% annual interest, compounded semi-annually. Which of the following represents the total amount of money, including interest, Alice would have in her account after 10 years?

A) 10,000 × (2X%)^10
B) 10,000 × (1 + X%)^10
C) 10,000 × (1 + 2X%)^10
D) 10,000 × (1 + X%)^20
E) 10,000 × (1 + 2X%)^20
\(CI = P(1+\frac{r}{2*100})^{2*n}\)

Or, \(CI = 10,000(1+\frac{2X}{2*100})^{2*10}\)

Or, \(CI = 10,000(1+\frac{X}{100})^{20}\), Answer must be (D)

Hey Abhishek009 this formula that you have written is for Amount, For CI we need to subtract Principal from it. I think there is a typo
