Appreciate some help in another question:

Judy had 200 coins in her saving box. There were only 10¢, 20¢ and 50¢ coins. First, she replaced all his 20¢ coins with 50¢ coins of the same value and there were 146 coins in the saving box. Then she replaced all his 10¢ coins with 50¢ coins of the same value and there were 66 coins left in the saving box. How many 50¢ coins were there in the box at first?

Thanks

Dont use the tutor name by Jamie Wong. She collect advance payment but keep changing her schld n timing. She is either late for lesson, MC or will msg u said she’s tired today n request for a day off! I stopped her service last Friday n still waiting for her to refund my $. I contacted her last Wednesday she said she is busy with classes, no time to transfer to me. How long does it take to make a Internet transfer? She said will do so over the weekend but until now still no sound no picture.


She is recommended by a agent, Janice tan. I MSG the agent to chase for payment n follow up by a phone call. Guess what? Agent did not pick up my call! No choice, I have to give them a deadline to transfer my refund to me, if not, I will make a police report! The agent replied ok

Irresponsible tutor n agent!!

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?
