Question

find the compound interest on rs.8000 for 1 1/2 years at 10% per annum if interest is being calculated half yearly

Answer 1

Answer:

Rs, 1,261

Step-by-step explanation:

P = Rs. 8000

Time = 1 and 1/2 years = 3/2 years

R = 10%

Amount after 3/2 years = Rs. P{ $(1 + R/100 * 2)^{2*t}$}

                                      = Rs.{ 8,000 $(1 + 10/200)^{2*3/2}$}

                                    = Rs.  {8,000 $(1 + 10/200)^{3}$}

                                     = Rs. {8,000 * 21/20 * 21/20 * 21/20}

                                      = Rs. 9,261

Therefore CI after 3/2 years = A - P

                                              = Rs. ( 9261-8000)

                                              = Rs. 1,261
