The total number of chocolate bars remains unchanged after Owen gives to Oscar.
Total number of chocolate bars
= 357 + 537
= 894
Total number of chocolate bars in the end
= 1 u + 1 u + 56
= 2 u + 56
2 u + 56 = 894
2 u = 894 - 56
2 u = 838
1 u = 838 ÷ 2 = 419
Number of chocolate bars that Owen must give to Oscar
= 537 - 419
= 118
Answer(s): 118
