The total number of beads remains unchanged after Sam gives to Archie.
Total number of beads
= 134 + 333
= 467
Total number of beads in the end
= 1 u + 1 u + 125
= 2 u + 125
2 u + 125 = 467
2 u = 467 - 125
2 u = 342
1 u = 342 ÷ 2 = 171
Number of beads that Sam must give to Archie
= 171 - 134
= 37
Answer(s): 37
