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

I didn't type that. Probably a guest impersonating me.

A guest impersonating a guest.   Is that your humor input?  Yes, it is mildly amusing.

 

But still no 'thank you'.

I read it as a total of 420 marbles put into box A and box B.

...  Some in box A and some in box B. 

That is why I could not do it.

 

Thanks aps.. 

 It does say a TOTAL of 420 marbles so it is badly worded.

It should have said 420 marbles are put into each of the two boxes.
