Question

1. Calculate the simple interest for the following : (a) p=rupee 7200,R=7.5 per annum,T=6 months​

Answer 1

Answer:

simple interest =rate of interest×time in year× principal/100

here principal =Rs 7200

rate of interest=7.5%

time=6 months=6/12 year=1/2 year

interest =7200×7.5×1/2×100Rs

=36×7.5Rs

=Rs 270
