Given: Roma borrowed Rs. 64000 from a bank for 1 ( 1\2 )years at the rate of 10 % per annum.

To find: Compare the total compound interest payable by Roma after 1 (1\2) years , if the interest is compounded half - yearly . ​

Solution:

  • Now we have given P = Rs 64000, R = 10% pa and n = 1.5 years
  • Now amount after n years will be:

                 A = P(1 + R/100 )^2n

  • Putting the values in it, we get:

                 A = 64000 x (1 + 10/200 )^2(1.5)

                 A = 64000 x (200+10/200 )³

                 A = 64000 x (210/200 )³

                 A = 64000 x (1.05 )³

                 A = Rs 74088

  • Now for Compound Interest we have:

                 CI = A - P

                 CI = 74088 - 64000

                 CI = Rs 10088

Answer:

               So the Compound Interest will be Rs 10088.
