Answer 1

Answer:

let the principle be x

s.i=p×r×t/100=x×5×2/100

x/100

amount=p×[1+r/100]^n

=x[1+5/100]^2

=x[100+5/100]^2

x[105/100]^2

x[21/20]^2

x×21/20×21/20

=x×441/400

441x/400

ci=a-p

441x/400-x

=41x/400

difference between simple interest and compound interest

ci-si=50

41x/400-x/10=50

41x-40x/400=50

x/400=50

x=50×400

x=20,000
