​

Answer 1

Answer:

ANSWER

Let the parts be RsA;Rs15,600−A

Simple Interest I=

100

PNR

For the first situation, Given,

P=RsA

N=5years

R=5 %

So, =>I=

100

PNR

=>I

1

=

100

A×5×5

=>I

1

=

100

25A

For the second situation, Given,

P=Rs15,600−A

N=6years

R=

2

9

%

So, =>I=

100

PNR

=>I

2

=

100

(15,600−A)×6×

2

9

=>I

2

=

100

(15,600−A)×27

Given, I

1

=I

2

=>

100

25A

=

100

(15,600−A)×27

25A=(15,600−A)×27

25A=421200−27A

=>52A=421200

=>A=Rs8,100

And other part =Rs15,600−Rs8,100=Rs7,500
