请问LIMA PULUH RIBU RUPIAH 50000元相当多少RMB?

Do you mean "Sepuluh Ribu Rupiah"? It's 印度尼西亚语 for
sepuleh pibu rupiah = 10,000 rupiah (rupiah= 印度尼西亚德元）

Currently:

10,000.00 IDR Indonesia Rupiahs = 9.15120 CNY
China Yuan Renminbi

1 IDR = 0.000915120 CNY
1 CNY = 1,092.75 IDR
Paper Notes:
100 Rupiah = Seratus Rupiah
500 Rupiah = Lima Ratu Rupiah
1,000 Rupiah = Seribu Rupiah
5,000 Rupiah = Lima Ribu Rupiah
10,000 Rupiah = Sepuluh Ribu Rupiah
20,000 Rupiah = Dua Puluh Rupiah
50,000 Rupiah = Lima Puluh Ribu Rupiah
100,000 Rupiah = Seratus Ribu R
那样可以算出9.15*5=45.75
