Step-by-step explanation:
Total money =12000Rs.
First investment =x Rs.
Second investment =(12000−x)Rs.
First income =
100
10
×x=
10
x
Second income =
100
12
(12000−x)
So
100
10x
+
100
12
(12000−x)=1280
⇒10x+144000−12x=128000
⇒144000−128000=2x
⇒x=
2
16000
=8000
12000−x=4000
Investments are 8000 & 4000 Rs.

Answer:
Let
R
s
.
x
was invested @10% and
R
s
.
(
12000
−
x
)
was invested @12%.
So by the problem
x
×
10
%
+
(
12000
−
x
)
×
12
%
=
1280
⇒
12000
×
12
%
−
x
×
2
%
=
1280
⇒
12000
×
12
−
x
×
2
=
128000
⇒
2
x
=
144000
−
128000
=
16000
⇒
x
=
8000
So
R
s
.8000
was invested @10% and
R
s
.
(
12000
−
8000
)
=
R
s
.4000
was invested @12%
