Let one part =x
∴ Other part =40000−x
For Part 1
r=10%,P=x
T=t (Let)
∴S.I=
100
PRT
=
100
x×10×t
=
10
xt
For Part 2
P=(40000−x)
R=6%
T=t
∴S.I=
100
(40000−x)×6×t
=
100
(40000−x)6t
ATP,
10
xt
+
100
(40000−x)6t
=
100
40000×7.5×t
⇒
10
xt
+
100
(40000−x)6t
=3000t×100
⇒10x+(40000−x)6=300000
⇒10x−6x+240000=300000
⇒4x=60000
⇒x=15,000
∴ Other part =40000−x=25,000
∴ Part 1: Part 2 =15,000:25000
=3:5
