The total number of chocolate bars remains unchanged after Glen gives to Japheth.
Total number of chocolate bars
= 347 + 655
= 1002
Total number of chocolate bars in the end
= 1 u + 1 u + 42
= 2 u + 42
2 u + 42 = 1002
2 u = 1002 - 42
2 u = 960
1 u = 960 ÷ 2 = 480
Number of chocolate bars that Glen must give to Japheth
= 655 - 480
= 175
Answer(s): 175
