The total number of sweets remains unchanged after Will gives to Ian.
Total number of sweets
= 434 + 531
= 965
Total number of sweets in the end
= 1 u + 1 u + 51
= 2 u + 51
2 u + 51 = 965
2 u = 965 - 51
2 u = 914
1 u = 914 ÷ 2 = 457
Number of sweets that Will must give to Ian
= 531 - 457
= 74
Answer(s): 74
