Raj, Siva and Paul had $700 altogether. Raj spent 1/3 of his money, Siva spent $52 and Paul spent twice the amount of what Raj spent. The three of them had the same amount of money left. How much did Raj have at first?
Solution
9 units + $52 ----- $700
9 units ----- $700 - $52 = $648
1 unit ----- $648 divided by 9 = $72
(Raj) 3 units ----- 3 x $72 = $216
Answer: Raj had $216 at first.
