Question

Calculate the amount and simple interest at the end of 4 years for principal of Rs.1200 at the rate of 12% per annum.

Answer 1

Answer:

We have,

(a) principal(p)=Rs1200

Rate(R)=12%

Time(t)=3year

S.I=  

100

P×R×T

​  

 

=  

100

1200×12×3

​  

 

=Rs432

amount=P+S.I

=1200+432

=1632

Step-by-step explanation:

Answer 2

Answer:

576 and 1776

Step-by-step explanation:

Simple interest = (P x T x R )/ 100

                        = ( 1200 x 4 x 12) / 100

                        = ( 12 x 4 x 12)

                        = 144 x 4 = 576

Amount = Principal + Simple interest = 1200 + 576 = 1776
