Explanation:
For first year, S.I. = C.I.
Now, Rs. 16 is the S.I. on S.I. for 1 year.
∴ Rs. 10 is S.I. on Rs. 100
∴ Rs. 16 is S.I. on (
10
100
×16)=Rs.160
∴ S.I. on principal for 1 year at 10% is Rs. 160.
∴ principal =(
10×1
100×160
)=Rs.1600.
Amount for 2 years compounded half yearly
=Rs.[1600×(1+

Answer:
Total Amount = 11664
Compound Interest= 10640
Explanation:
6 months = 1024+512 = 1536
12 months = 1536+ 768 = 2304
18 months = 2304 + 1152= 3456
24 months = 3456 + 1728 = 5184
30 months = 5184 + 2592 = 7776
36 months = 7776 + 3888 = 11664
CI = 11664 - 1024 = 10640
