The total number of sweets remains unchanged after Japheth gives to Albert.
Total number of sweets
= 325 + 628
= 953
Total number of sweets in the end
= 1 u + 1 u + 55
= 2 u + 55
2 u + 55 = 953
2 u = 953 - 55
2 u = 898
1 u = 898 ÷ 2 = 449
Number of sweets that Japheth must give to Albert
= 628 - 449
= 179
Answer(s): 179
