$3600

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:

$x + (- 1600 - (2x - 3200)/5)$ = $x/3$

$3x + 3(- 1600 +(-2x + 3200)/5) = x$

$3x + (- 4800 + (-6x +9600)/5) = x$

$3x + (-4800 -1.2x + 1920) = x$

$2x = 4800 + 1.2x - 1920$

$0.8x = 2880$

$x = 3600$
