The total number of balls remains unchanged after Neave gives to Cole.
Total number of balls
= 185 + 360
= 545
Total number of balls in the end
= 1 u + 1 u + 67
= 2 u + 67
2 u + 67 = 545
2 u = 545 - 67
2 u = 478
1 u = 478 ÷ 2 = 239
Number of balls that Neave must give to Cole
= 239 - 185
= 54
Answer(s): 54
