The total number of beads remains unchanged after Julian gives to Oscar.
Total number of beads
= 332 + 417
= 749
Total number of beads in the end
= 1 u + 1 u + 73
= 2 u + 73
2 u + 73 = 749
2 u = 749 - 73
2 u = 676
1 u = 676 ÷ 2 = 338
Number of beads that Julian must give to Oscar
= 338 - 332
= 6
Answer(s): 6
