Answer 1

Answer:

1)C.I.=(1600(1+5/100)^3)-1600

=1600×21×21×21/(20×20×20)-1600

=1852.20-1600

=252.20rs is the interest.

2)

principle=25000.

rate=10%.

time=1/2yr.

interest for first part=

25000×10×1/2×1/100=1250.

amount=principle +interest.

=25000+1250

=26250.

so,principle for 1/4 year is now 26250.

interest for next part=26250×1/4×10×1/100

=656.25

amount for second part

=principle +interest

=26250+656.25

=26906.25.

compound interest=final amount-original principle

=26906.25-25000

=1906.25.

final amount=26906.25

compound interest =1906.25
