Question

please answer this question this is very urgent who give right answer first I Mark it branliest

Answer 1

Given principal = 12800,

Rate of interest r = (15/2)% = (15/4)% per half-year,

Time n = 2 years.

Now,

We know that Amount A = P(1 + r/100)^n

                                          = 12800(1 + 15/400)^2

                                          = 12800(415/400)^2

                                          = 12800(172225/160000)

                                          = 13778.



We know that compound interest = Amount - Principal

                                                         = 13778 - 12800

                                                         = 978.




Hope this helps!
