The total number of beads remains unchanged after Sam gives to Valen.
Total number of beads
= 246 + 387
= 633
Total number of beads in the end
= 1 u + 1 u + 53
= 2 u + 53
2 u + 53 = 633
2 u = 633 - 53
2 u = 580
1 u = 580 ÷ 2 = 290
Number of beads that Sam must give to Valen
= 290 - 246
= 44
Answer(s): 44
