The total number of balls remains unchanged after Elijah gives to Vaidev.
Total number of balls
= 196 + 254
= 450
Total number of balls in the end
= 1 u + 1 u + 54
= 2 u + 54
2 u + 54 = 450
2 u = 450 - 54
2 u = 396
1 u = 396 ÷ 2 = 198
Number of balls that Elijah must give to Vaidev
= 198 - 196
= 2
Answer(s): 2
