Answer 1

wait I'm answering.... plzz

P =Rs.12800

P =Rs.12800Rate of interest =10 %

$interest \: of \: first \: year = \frac{prt}{100}$

$= \frac{12800 \times 10 \times 1}{100} = rs.1280$

Amount after first year=12800+1280=Rs.14080

For Second year

For Second yearPrincipal =Rs.14080

For Second yearPrincipal =Rs.14080R =10%

For Second yearPrincipal =Rs.14080R =10%T =1 year

$interest \: of \: second \: year = \frac{prt}{100}$

$= \frac{1480 \times 10 \times 1}{100} = rs.1408$

Amount = Rs. 14080+ Rs. 1408= Rs. 15488

For third year
