The total number of beads remains unchanged after Elijah gives to Julian.
Total number of beads
= 149 + 456
= 605
Total number of beads in the end
= 1 u + 1 u + 71
= 2 u + 71
2 u + 71 = 605
2 u = 605 - 71
2 u = 534
1 u = 534 ÷ 2 = 267
Number of beads that Elijah must give to Julian
= 267 - 149
= 118
Answer(s): 118
