Step-by-step explanation:
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
