Answer 1

Step-by-step explanation:

R=12.5% but 6.25%(half yearly)

6.25%=1/16

First half second half

256×1/16 16+1/16×16

16 16+1=17

Total interest =16+17=33

Amount =256+33=289

Answer 2

256 will amount to Rs.289 in 1 year at 12+1/2 per annum when the interest is compounded half yearly​

Step-by-step explanation:

Principal = Rs.256

Time = 1 year

No. of compounds per year n = 2

Rate of interest = $12\frac{1}{2} = \frac{25}{2}\%$

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

A = Amount

P = Principal

r = rate of interest

n = No. of compounds

t = time

Substitute the values in the formula :

$A= 256(1+\frac{25}{200 \times 2})^{2}$

A= 289

Hence 256 will amount to Rs.289 in 1 year at 12+1/2 per annum when the interest is compounded half yearly​
