Answer 2

Answer:

4(I) r=10%

Step-by-step explanation:

let r%=r

principle=p=6500

amount=7865

time=2years=n

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

7865=6500(1+r/100)^2

7865/6500=(100+r/100)^2

121/100=(100+r/100)^2

(11/10)^2=(100+r/100)^2. [cancelling square from both sides]

11/10=100+r/100

11×100/10=100+r

110=100+r

110-100=r

r=10%
