Step-by-step explanation:

1000(1 + \frac{4}{100} ){3}1000(1+

)3
on t we write 3 because in compounded half yearly we have to distribute years so one and half year iss equal to 3 half years
1000 \times \frac{104}{100} \times \frac{104}{100} \times \frac{104}{100}1000×

\frac{1124864}{1000}
1000
1124864
1124.8641124.864
so we subtract the principal value by amount soo
1124.86 - 10001124.86−1000
124.86124.86
so 124.86 is the answer...
Answer:
Calculate Accrued Amount (Principal + Interest) A = P(1 + r/n)nt
Calculate Principal Amount, solve for P. P = A / (1 + r/n)nt
Calculate rate of interest in decimal, solve for r. r = n[(A/P)1/nt - 1]
Calculate rate of interest in percent. R = r * 100.
Calculate time, solve for t.
