Answer 1

Answer:

Simple interest =P×R×T100

where P is the principal amount , R is the rate and T is time.

1. P=4500,R=4,T=0.5

applying in formula, simple interest=Rs.90

2.1. P=12000,R=18,T=13

applying in formula, simple interest=Rs.720

3.1. P=1000,R=10,T=0.2

applying in formula, simple interest=Rs.20
