The interest rate would be 3.98% when compounded quarterly. Given the data, the interest rate is r₂ = 4%. As everything else remains the same let us use the formula

A( quarterly) = A (Semiannually)

[tex]P(1+\frac{r1}{n1}) ^{n1t} =P( 1+ \frac{r2}{n2}) ^{n2t}[/tex]

Simplifying the equations we get:

[tex](1+\frac{ri}{n1}) ^{n1} = (1+\frac{r2}{n2}) ^{n2}[/tex]

Substituting n1 = 4 (quarterly:) and n2 = 2(semiannually)

Then [tex](1+\frac{ri}{4}) ^{4} = (1+\frac{0.04}{2}) ^{2}[/tex]

[tex](1+\frac{ri}{4}) ^{2} =1.02[/tex]

[tex](1+\frac{ri}{4}) =1.009950[/tex]

[tex]\frac{r_{1}}{4}[/tex] = 0.009950

[tex]r_{1}[/tex] = 0.03980

[tex]r_{1}[/tex] = 3.98%

There are various types in which compounding can be done like monthly, quarterly, semiannually, annually, and continuously compounding.

The factors that will affect the amount of compound interest will be:

(1) The principal amount

(2) the interest rate

(3) The time period

(4) |The type of compounding

(5) The interest of the previous amount.
