Question

3. Find the amount and the compound interest on
12800 for 1 year at 7
% per annum
compounded semi-annually.​

Answer 1

Answer:

amount =14654.72 and

Compound interest =1854.72

Step-by-step explanation:

Here, n=2(2half yearly)

A=12800(1+7/100)^2

=12800(107/100)^2

=12800*107/100*107/100

=128*107*107/100

=1465472/100

=14654.72

A=14654.72

therefore, compound interest =amount -principle

C I =14654.72-12800

CI. =1854.72
