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?
+118687 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.
+118687 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?

+313 420 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
