Answer 1

Answer:

r =9%

Step-by-step explanation:

given

p=3560

I=961.20

A=4521.20

T =3

R =?

for S.i = 4521.20-3560

=961.20

as we all know

$s \: i = \frac{p \: \times n \times r}{100}$

put all the values

$961.20 = \frac{3560 \: \times 3 \times r}{100}$

961.20 x 100 = 3560 x 3 x r

$\frac{96120}{3560 \times 3} = r$

R = 9%
