Answer 1

principal = 9000

rate = 10%per annum = 10/2% =5%per half years.

time = 18months = 3 half years.

$amount \\ = 9000 \times {(1 + \frac{5}{100} )}^{3} \\ = 9000 \times 1.05 \times 1.05 \times 1.05 \\ = 10418.625$

amount paid at the end of first 6 months = 2500rs

amount paid at the end of second 6 months =2500rs

amount paid at the end of last 6 months =10418.625 - (2500+2500)rs

=10418.625 - 5000 rs

=5418.625 rs
