Bafflers?

Hi;

Due to increased traffic in my other two problem threads I have started this one. It will contain problems that appear difficult but are not. Or maybe, just not as difficult as the other two threads.

Baffler #1

An opaque jar contains100 marbles. 50 of them are blue and 50 are white. 25 marbles are picked out of the jar at random. They are discarded and 25 blue marbles are put into the jar. This process is done 9 more times. What percentage of white marbles remains?

A says) 4%

B says) About 2.8%

C says) I agree with either (A or B) or (A and B) I am not sure.

D says) C is right.

E says) B is close but he does not have an exact answer. I have a method.

B says) I have a method now!

Who is closest and can you find E's method?

I do not mind at all. But it is a change in your habits.

Re: Bafflers?

Hi phrontister;

I understand perfectly. It is okay to tell all your ideas and it is welcomed by me. I also thank you for looking at the problem.

I was never late for school.

Re: Bafflers?

Hi bobbym

That's a little farfetched (if that word can be used here). Never is a strong word, unlike ever.

As farfetched as it may seem to you nevertheless it is the truth.

Re: Bafflers?

So you were always either on time, or didn't show up at all?

Re: Bafflers?

That is correct! Some classes were so delightful I would never miss them. Others bored me to tears.
