Answer 1

Answer:

Given that,

Time=4 years

principleRs.6500

Amount=Rs.8840

Interest=8840−6500=Rs.2340

We know that,

S.I=

100

p×r×t

2300=

100

6500×r×4

r=

6500×4

2300×100

=9

then,

P=16000

A=1816

S.I=216

S.I=

100

p×r×t

216=

100

1600×9×t

t=

1600×9

216×100

= 23

Then,

We get t=2

21years.
