The total number of balls remains unchanged after Neave gives to Ryan.
Total number of balls
= 224 + 363
= 587
Total number of balls in the end
= 1 u + 1 u + 57
= 2 u + 57
2 u + 57 = 587
2 u = 587 - 57
2 u = 530
1 u = 530 ÷ 2 = 265
Number of balls that Neave must give to Ryan
= 265 - 224
= 41
Answer(s): 41
