Question

what is the compound interest on Rs.15,000 for 2 years at 5% per annum compounded annually​

Answer 1

i)

A=P(1+100r)n=15000(1+10010)2=Rs18150

CI=A−P=Rs3150

(ii)

A=P(1+100r/m)n∗m=156250(1+1008/2)1.5∗2=Rs175760

CI=A−P=Rs19510

(iii)

A=P(1+100r/m)n∗m=100000(1+1004/4)0.75∗4=Rs103030.1≈Rs103030

CI=A−P=Rs3030
