HELP ME.... :?:

Appreciate your assistance, Thanks in advance...

Raja and Devi had the same amount of money. After Raja had donated $130 and Devi had donated $100 to the Japanese earthquake relief work, Raja had 1/4 as much money as Devi.
How much money did each child have at first?

Hi

Besides MD, P5 kids may also use \"Systematic Listing\".

Hope this helps.

Best wishes
