Answer 2

Answer:

945.75

Step-by-step explanation:

First we will find out Principal :-

S.I=P×R×T/100

1200=P×5×3/100

P=1200×100/5×3

P=₹8,000

Now, we will find out compound interest :-

A=P(1+R/100)³

A=8000(1+5/100)³

=8000(21/2×21/2×21/2)

=8000×9261/8

=9261000

C.I=Amount-Principal

C.I=9261000-8000

=₹9,253,000
