Question

Find the Compound Interest


a) Principal - 4000, Time = 2 years, Rate = 10% per annum


b) Principal = 18000, Time = 2 years, Rate = 15% per annum​

Answer 1

Answer:

4000(1+(10/100)²)

4000(11/10)²

4000×11/10×11/10

40×121

4840

ci=4840-4000

ci=840

18000(1+(15/100)²)

18000(23/20)²

18000×23/20×23/20

180×23×23/2×2

23805

ci=23805-18000

ci=5805
