Question

14. Calculate the amount
and the compound intrest
a sum of 1000 at 10%
p.a compounded annually
3 years
.​

Answer 1

Answer:

Here, P= 1000, r=10% per annum

and n=18 months =1218​ years =23​ years =121​ years

∴ Amount after 18 months =P[1+21​(100r​)]2n

                                  =1000[1+21​(10010​)]2×23​

                                  =1000(1+20010​)3

                                  =1000(2021​)3

                                  =1000×2021​×2021​×2021​

                                  = 1157.625

                                  = 1157.63

C.I. =A−P

     =1157.63−1000= 157.63

Answer 2

Answer:

amount  = 1000 x 10 % x 3 / 100 = 10000 x 3 divided by 100 = 30000 divided by 100 = 300
