The total number of balls remains unchanged after Perry gives to Zeph.
Total number of balls
= 108 + 281
= 389
Total number of balls in the end
= 1 u + 1 u + 53
= 2 u + 53
2 u + 53 = 389
2 u = 389 - 53
2 u = 336
1 u = 336 ÷ 2 = 168
Number of balls that Perry must give to Zeph
= 168 - 108
= 60
Answer(s): 60
