        After reading the post, I do not understand the problem's question.

        How many beads did they have TOGETHER ? SEPARATELY ?

        If SEPARATELY, then AT THE BEGINNING or AT THE END ?


        In this sense, the post is DEFECTIVE  (and deserves serious punishment).

        In order for it would make sense, I will consider the question in this form:

              How many beads did EACH of THEM have AT THE BEGINNING ? 


Since "Jenny had 3/5 as many beads as Kelly", we can think that Kelly had 5x beads, while Jenny had 3x beads.


After Kelly gave Jenny 24 beads, they have:  Kelly  5x-24 beads;  Jenny  3x+24 beads.


The total beads is 5x + 3x = 8x.


The last condition of the problem states that


    3x + 24 = %283%2F4%29%2A%288x%29.


Simplify this equation and find x


    3x + 24 = 3*(2x)

    3x + 24 = 6x

         24 = 6x - 3x 

         24 = 3x

          x = 24/3 = 8.


ANSWER.  Originally, they had  8*5 = 40 beans (Kelly)  and  8*3 = 24 beans (Jenny). 

         If you want to know the total, you may add these numbers.

Solved and thoroughly explained.

The distribution of the beads between the two girls changes in the problem, but the total number of beads does not change; there is nothing defective about the problem as stated.

Given that Jenny had (i.e., started with) 3/5 as many beads as Kelly, let the numbers of beads they started with be 3x for Jenny and 5x for Kelly. The number of beads they had together is then 8x.

After Kelly gave 24 beads to Jenny, Jenny had 3x+24 beads, which was 3/4 of all the beads:

3x%2B24+=+%283%2F4%298x
3x%2B24=6x
24=3x
x=8

ANSWER: The number of beads they had (both at the beginning and at the end) was 8x=64.
