A total of 420 green marbles and red marbles were put into Box A

and Box B respectively. There were 1 1/2 times as many red marbles as

green marbles. Some yellow marbles were put into Box B. For every

3 green marbles in Box A, 16 blue ones were added into Box A.

Box A then had four times as many marbles as Box B. What was the

ratio of the number of yellow marbles to the number of blue marbles?

I have looked at this question and I do not think that there is enough information given.

When you get the answer (preferably with working) can you please share it with this forum.

Yes I understand that, I was not accusing you of leaving anything out.

I just wonder if the original asker of the question left something out.

I assume you copied and pasted the question?

420 green and red marbles Put into box A and

Box B respectively

1 1/2 times as many red marble as green

marble

-> Let green marble x

3/2x + x = 420

5x = 840

x = 168 = green marble in Box A

Red marble = 252 in Box B

Some yellow marble in Box B

Let's say y no. of yellow marble in B added

for every 3 green marbles in A, 16 blue were

added in Box A

-> green marble in A = 168

for every 3, 16 blue added = 168/3 * 16

= 896 blue added

Now Box A had four times as B

896 + 168 = (252 + y) 4

252 + y = 266

y = 14

Yellow added were 14

now, what is the ratio of number of yellow

to the number of blue marbles

= 14/896

= 1/64

= 1:64
