​

Answer 1

Answer:

here your answer.....

Step-by-step explanation:

We know that

A = P(1 + r/100)^n

here

A = 2315.25

P = 2000

n = 2n = 2*1 = 2 (compounded half yearly)

r = r/2 [compounded half yearly]

Now

2315.25 = 2000(1 + r/200)^2

1 + r/200 = √(2315.25/2000) = 1.075

r/200=1.075-1

r/200 = 0.075

r = 0.075*200 = 15%

hope it' will helps you...............
