Shortcut guys,
1600*5/100*6/12 = 40 then after 6 months 1600+1600 = 3200 & also 40 will be interest calculate.
3200*5/100*6/12 = 80.
40*5/100*6/12 = 1.
= 40+80+1 = 121 Answer.
1600*5/100*6/12 = 40 then after 6 months 1600+1600 = 3200 & also 40 will be interest calculate.
3200*5/100*6/12 = 80.
40*5/100*6/12 = 1.
= 40+80+1 = 121 Answer.

Hello @Preeti.
In first case it is 1 year because its from 1st Jan to end of the year so its of 12 months = 1 year.
In sec case it is 1/2 year because its from 1st July to end of the year its of 6 months = 1/2 year.
Hope you ll get.

1st Jan-First Half Yr 1600 x 5/100 x 6/12 = 40.00.
1st Jan-Second Half Yr (1600+40)x 5/100 x 6/12 = 41.00.
1st Jul-second Half Yr 1600 x 5/100 x 6/112 = 40.00.
_______
Total Int = 121.00.

SI : 625 x 4% x 2yr = ---------------------------------- 50.00.
CI : 625 x 4% x 1st Yr ------------------ 25.00.
(625+25) x 4% x 2nd yr ------------- 26.00.
------ -------
Total 51.00 50.00.
Difference between SI & CI (51.00 - 50.00) 1.00.
CI : 625 x 4% x 1st Yr ------------------ 25.00.

Hi,
What does "5% compound interest calculated on half-yearly basis" actually mean?
This 5% interest is, interest per annum.
Or interest per 6 months?
