Answer 2

The amount is Rs.13230.

The compound interest is Rs.1230.

Step-by-step explanation:

To find : The amount and the C.I. on ₹ 12,000 at 10% per annum compounded half-yearly ?

Solution :

Using compound interest formula,

$A=P(1+\frac{r}{n})^{nt}$

Where,

Principal (P) = ₹ 12,000

Rate (r) = 10% =0.1

Time (t) = 1 years

Substitute the values,

$A=12000(1+\frac{0.1}{2})^{1\times 2}$

$A=12000(1+0.05)^{2}$

$A=12000(1.05)^{2}$

$A=12000\times 1.1025$

$A=Rs.13230$

The amount is Rs.13230.

C.I. = Amount – Principal

C.I.= ₹ 13230 - ₹ 12000

C.I. = ₹1230

The compound interest is Rs.1230.
