Answer 2

Answer:

n = 1/2

Step-by-step explanation:

Given CI = 6,560

CI = P(1 + i)ⁿ

P = 6,400

i = 0.05

Compounded semi annually

CI = P(1 + i)ⁿ

6,560 = 6,400( 1 + $\frac{0.05}{2}$ )²ⁿ

$\frac{6,560}{6,400} = (\frac{2.05}{2})$²ⁿ

1.025 = 1.025²ⁿ

If bases re same power are also same and vice versa

2n = 1

n = 1/2
