The total number of beads remains unchanged after Asher gives to Fabian.
Total number of beads
= 138 + 349
= 487
Total number of beads in the end
= 1 u + 1 u + 113
= 2 u + 113
2 u + 113 = 487
2 u = 487 - 113
2 u = 374
1 u = 374 ÷ 2 = 187
Number of beads that Asher must give to Fabian
= 187 - 138
= 49
Answer(s): 49
