If Mary collected twice the number of red marbles collected by Jenny, she got 2*30 = <<2*30=60>>60 red marbles.
Anie collected 20 more red marbles than Mary, which is 60+20 = 80 red marbles.
The total number of red marbles is 60+80+30 = <<60+80+30=170>>170 red marbles.
If Anie collected twice the number of blue marbles collected by Jenny, then she got 2*25 = <<2*25=50>>50 blue marbles.
Mary collected half the number of blue marbles collected by Anie, thus 1/2*50 = 25 marbles
The total number of blue marbles collected is 50+25+25 = <<50+25+25=100>>100 blue marbles
