1. Find the compound interest on 4000 for 1 years at 5% per annum compounded half-yearly. interest on 10,000 for one year at 6% per annum, if the interest is
compounded half-yearly​

Answer 1

Step-by-step explanation:

Amount =4000

YEARLY interest =5%

Half year interest =2.5%

interest =4000(1+0.025)^2-4000=4202.50-4000

interest =202.50

Amount =10000

YEARLY interest =6%

Half year interest =3%

interest =10000(1+0.03)^2-10000=10609-10000

interest =609

Answer 2

Answer:

here is your answer.....

formula of compound interest calculated half yearly : A = P ( 1 + R/200 )ⁿ

Principal,P = 4000

Rate of interest , R= 5%

Time period , N = 1

Theref0ore

A = 400 ( 1 + 5/200 )¹

= 4000 ( 205/200)¹

= 4000*205/200

= 4100

CI = A - P

= 4100- 4000

= ₹100

2) P = 10000

R = 6%

N = 1

A = P ( 1 + R / 200 )ⁿ

10000(1+6/200)¹

10000(206/200)¹

10000*206/100

100*206

20600

CI = A - P

= 20600 - 10000

= 10600
