Answer:
Lets say "x" to "Savings";
x
−
(
1600
+
(
2
x
−
1600
5
)
)
=
x
3
(Because x is total amaount of savings and he spent $1600 so now he has
2
÷
5
of the total amount - $1600)
(
x
÷
3
Because he has
1
÷
3
of his original amount of savings)
So what is x? Its:
x
+
(
−
1600
−
2
x
−
3200
5
)
=
x
3
3
x

(

−
2
x
+
3200
5
)
=
x
3
x
+
(
−
4800

x
+
9600
5
)
=
x
3
x
+
(
−
4800
−
1.2
x
+
1920
)
=
x
2
x
=
4800
+
1.2
x
−
19200.8
x=2880
x=3600
