The total number of beads remains unchanged after Owen gives to Brandon.
Total number of beads
= 193 + 324
= 517
Total number of beads in the end
= 1 u + 1 u + 87
= 2 u + 87
2 u + 87 = 517
2 u = 517 - 87
2 u = 430
1 u = 430 ÷ 2 = 215
Number of beads that Owen must give to Brandon
= 215 - 193
= 22
Answer(s): 22
