Answer:

follow @_mprningztar_

Step-by-step explanation:

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
