Sorry for the late reply.
This is Guess and Check Method. I must say this question is a higher AO3 level question.
The relation ship of the 2 variables is based on
2 sets of ratios making Guess and Check at a more difficult level.
The other method will be using algebraic equation involving 2 unknown. It will be more abstract than Guess and Check.
