Question 1184327
.
Out of a salary of $4500, I kept 1/3 as savings. 
Out of the remaining money, I spend 50 % on food and 20 % on house rent. 
How much do I spend on food and house rent?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



            I have another solution and another answer, different from that of @Boreal.



<pre>
Out of the salary of $4500, one third, or $1500 goes to savings.


The remaining amount is $4500 - $1500 = $3000.


Of the remaining $3000, 50%, or $1500, is spent on food,


                    and 20%, or  $600, is spent on rent.


<U>ANSWER</U>.  $1500 is spent on food.   $600  is spent on rent.



         Notice that the sum  $1500 + $1500 + $600 = $3600, which is less than $4500,

         so  (1)  my solution is not self-contradictory, and 

             (2)  allows the room for other spendings, like gas, transportation, paying insurances, making gifts etc.

Solved.
