The total number of balls remains unchanged after Luke gives to Asher.
Total number of balls
= 315 + 392
= 707
Total number of balls in the end
= 1 u + 1 u + 51
= 2 u + 51
2 u + 51 = 707
2 u = 707 - 51
2 u = 656
1 u = 656 ÷ 2 = 328
Number of balls that Luke must give to Asher
= 328 - 315
= 13
Answer(s): 13
