One-quarter 82195

I have 100 marbles. One-quarter of them are white, and 3 fifths of the rest are blue. 1 third of those that are neither blue nor white are red, and the rest are green. How many marbles do I have?

Correct answer:

a =  25
b =  45
c =  10
d =  20

Step-by-step explanation:

n=100 a=n/4=100/4=25
z=na=10025=75 b=53 z=53 75=53 75=5225=45
