4500 x (1.01)14 = 5172.63
Semiannually over two years is equivalent to 4 periods. If the interest is 12% every 6 months, then the amount of interest is It is 8000*[(1.12)4 -1] =4588.15
$35144.44
25000 x (1.02)14 = 32976.97. For comparison, compounded annually would give 25000 x (1.04)7 = 32898.29, not a huge difference but worth having!
$280.51
1000 x (1.025)8 which is $1218.40.
$5,249.54
It is 20000*(1.07)^60 = 1158928.54
After 5 years, 20000 at 7% per annum compounded semiannually will be 20000*(1 + 0.5*7/100)2*5 = 20000*(1.035)10 = 28211.98
4500 x (1.01)14 = 5172.63

Semiannually over two years is equivalent to 4 periods. If the interest is 12% every 6 months, then the amount of interest is It is 8000*[(1.12)4 -1] =4588.15
800 x (1.04)6 ie Rs1012.26
9.5% semi-annually = 19.9025% annually.After 10 years 1200*(1.199025)^10 = 7369.93
You should have 5976.51 provided the fractional units of interest earned are also rolled into the capital.
It will take 11.9 (or 12) years.
I haven't gotten the answer to that test question either....the choices seem wrong
