Answer 1

Answer:

Formula

A = P(1 + \frac{r}{n})^{nt}

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Answer 2

CI =P(100+r/100)^n-P -for annually

CI=P(200+R/200)^2n-P -for semi annually or half yearly

CI=P(400+R/400)^4n-P - for 1/4 year
