Question

find the compound interest if:- principle=27000 rate=9.5% time=2.5year

Answer 1

When interest is compounded Annually say 2.5 years.
Amount = P 1 + R 3
x 1 + R
100 100

Answer 2

P=27000, r = 9.5%  for half- year = 9.5/2 = 4.75%  T= 2.5 year (for half -year) n =5
formula 
C.I  =P(1+ r/100)^n - P
      = 27000 (1 + 4.75/100)^5 - 27000
      =  27000 (1.0475)^5 - 27000
      =  27000 * 1.2612 - 27000
      =  34052.40 - 27000
   C.I   =Rs.  7052.40
