Total number of beads that Esther and Gwen shared = 100%
If Esther gave 310 beads to Gwen, both would have the same number of beads.
Number of beads that each would have in the end
= 100% ÷ 2
= 50%
Number of beads that Esther gave to Gwen
= 81% - 50%
= 31%
31% → 310
1% → 310 ÷ 31 = 10
Number of beads that Gwen had
= 19%
= 19 x 10
= 190
Answer(s): 190
