The total number of beads remains unchanged after Asher gives to George.
Total number of beads
= 306 + 442
= 748
Total number of beads in the end
= 1 u + 1 u + 110
= 2 u + 110
2 u + 110 = 748
2 u = 748 - 110
2 u = 638
1 u = 638 ÷ 2 = 319
Number of beads that Asher must give to George
= 319 - 306
= 13
Answer(s): 13
