उत्तर

₹ 820

Explanation;

Hint:

Compound interest (C.I.) = Amount – Principal

Amount = `"P"(1 + "r"/100)^(2"n")` ...[2n as it is compounded half yearly]

r = 10% p.a, for half yearly r = `10/2` = 5

∴ A = `8000(1 + 5/100)^(2 xx 1)`

= `8000 xx (105/100)^2`

= 8820

C.I. = Amount – Principal

= 8820 – 8000

= ₹ 820
