I am not sure if this is the right answer. Here u assumed both bags A and B have same amount of marbles (ie. x) which may not be the case.raunekk wrote:A)
r:w:b= 2x:6x:9x
B)
r:w=1x:4x
total W marbles = 6x+4x=10x=30
x=3
from A,
r = 2x = 6
hence D

but i think there is no other information to solve completely
and also
there is no choice such as "insufficient info"
so 6 sounds logicalThanks
