Answer 1

Answer:

Find the compound interest

(iv) P = Rs 2560; R = 12½%per annum, n= 1 year (Interest payable half-yearly)

Answer 2

Answer:

330rs

Step-by-step explanation:

AMOUNT=

$p(1 + \frac{r}{ {100}})^{n}$

principal =rs2560

rate=12½% per annum here we only have to fund ½ yearly compound interest so we will divide the rate with 2

=

$12 \frac{1}{2} \% \div 2 = \frac{25}{2} \% \times \frac{1}{2} = \frac{25}{4} \%$

time=1year which can we DEVIDED into 2 equal halves =2half years

.

SOLVING THE QUESTION

$2560(1 + (\frac{25}{4} \times \frac{1} {100}))^{2} \\ = 2560(1 + {\frac{1}{16} )}^{2} \\ = 2560 \times \frac{17}{16} \times \frac{17}{16} = 2890$

AMOUNT =RS 2890

COMPOUND INTEREST =AMOUNT-PRINCIPAL

=2890 -2560=330
