Hey Marco, let me help you out!
We do 400-160=240 so we take out the red marbles
Then 75% of 240 are the green marbles, so 240x75%=180
180/400=45%
45% is the answer

For q 59 it's also super easy.
60% of 600 is 360, which are the people with glasses. Later on 200 ppl join with 160 spectacled students. So that brings the total spectacled students to 520 and the total students to 800.
520/800=0.65, convert that to a percentage by going up 2 decimal places and you get 65%
