R:G:Y = 6:15:5

Total marbles are 26x.

52 and 182 can be the only possibilities. As 'x' should be an integer 24 cannot be the total number of marbles.

Explanation:
As we know R/G=2/5 ; Y/R=5/6
From above we know: 6Y=5R=2G=X (Let)

X/2 + X/5 + X/6 = (should be eqaul to Option A,B,C . So that X value should be integer)
26X/30= 24
X Not having Integer Value (not Possible)
26X/30=52
Possible. X is integer.
26X/30=182
Possible, X is integer.

IMO-D

Please give kudos, if you find my explanation Good Enough
