1,000(3 + 1.056)
1,000(1+3(0.056)
1,000[1+(0.056)^3]
1,000(1.056)^3


the formula is CI=P(1+r/100)^t

in this case i think E is the ans

It should be Amount instead of CI

CI amount calculated as below:

\(Amount = P (1+\frac{r}{100})^n\)

CI = Amount - P

1000 * 1.056 * 1.056 * 1.056 = 1000 * 1.056^3. E.
