1. Calculate the amount and the compound interest on 6250 for 2 years at 12% per
annum, compounded annually.
2. Find the amount and C.I. for 6400 in 2​

Answer 1

Answer:

1) 1590

2)1628.1

Step-by-step explanation:

1) CI= p[1+ R/100]^t - p

principal=p, time= t ,r = rate of interest

CI= 6250[1+ 12/100]^2 -6250

CI=1590

amount= CI +P= 7840

2)CI=6400[1+12/100]^2- 6400

=1628.1

amount= 1628.1+6400

8028.1
