If t is total, then:
0.2 * t = blue; remaining 80% or 0.8 * t = r + w;
One quarter or 1/4 of the REMAINING are red which is 0.8 * t * 1/4.
We have remaining 0.8 * t * 3/4 for white.
One-third of white marbles is (0.8 * t * 3/4) / 3 = 0.8 * t * 1/4 = number of red marbles.
Answer is C.

i tried doing this taking 45 marbles , but i am not getting C as an answer
20% of 45 is 9(blue marbles)
1/3rd of the remaining i.e 1/3*36 is 12(red marbles)
remaining are white i.e 24 marbles...1/3 of white marbles is 1/3*24 is 8
so, A>B
