Answer 1

principl=7200
rate=?
time=4year
interest=3024
p×r×t/100=3024
7200×r×4/100=3024
72×4×r=3024
r=3024/72×4
r=10.5%

Answer 2

Answer:

Step-by-step explanation:

P = 7200

T = 4years

I = 3024

R = ?

I = P×R×T/100

3024 = 7200×R×4/100

3024 = 72×R×4

3024 = 72 ×4 ×R

3024 = 288×R

R = 3024/288

R = 10.5
