part a) is incorrect. 'The three children had the same number of sweets in the end' refers to each child having an equal number of sweets, not Ruby + Steve = Max

As a result of this misconception it is not known how much Ruby and Steve have in the end, since only their total is known. So how much Steve had at first cannot be determined as well.

(In your working, Ruby has 192 sweets in the end but Ruby + Steve has 160 in the end. So that's not possible since she cannot have more than their combined total)
