For some reason i was fixated with not knowing the value of yellow balls, Nevertheless

Given R = 3B

Statement 1
B = G - 5, you cannot do much with this, since no relationship is present.

Statement 2
R = 3/2 G
Here you can get a relationship between B = 1/2 G, again you cannot do much here.

After combining both the statements
1/2 G = G - 5
G = 10

In such questions we can also see that we need two equations if we have two variables . knowing X Y and Y Z we can't find much .
But if we get one more equation for X Z then we can find the answer .
