The total number of balls remains unchanged after Elijah gives to Michael.
Total number of balls
= 202 + 424
= 626
Total number of balls in the end
= 1 u + 1 u + 134
= 2 u + 134
2 u + 134 = 626
2 u = 626 - 134
2 u = 492
1 u = 492 ÷ 2 = 246
Number of balls that Elijah must give to Michael
= 246 - 202
= 44
Answer(s): 44
