Answer 1

Answer:

Step-by-step explanation:Given Principal =64000.           Rate of interest = 20% P.A.           n  = 1.5 years.We know that A = P(1 + r/100)^nWhen the interest is compounded semi-annually.A = P(1 + r/200)^2n    = 64000(1 + 20/200)^3    = 64000(11/10)^3    = 64000 * 1.331    = 85184.We know that CI = A - P                             = 85184 - 64000                             = 21184.We know that SI = PRT/100                            = 64000 * 20 * 3/100 * 2                            = 64000 * 60/200                            = 19200.Difference between Simple Intrest and Compound Intrest = 21184 -19200                                                                                                  = 1984.

Hope this helps!
