If the person has only one hour to study, he should choose to study Chemistry as the total marks by studing 1 hour chemistry and 0 hours biology = 62+ 56=118 which is greater than the score that will be obtained by studying 1 hour biology and 0 hours chemistry.
If the person has two hours , he has three senarios a) 2 hours chemistry and 0 hours biology: Total score= 67+56 = 123 b) 2 hours biology and 0 hours chemistry: Total score= 55+66 = 121 c) 1 hour biology and 1 hour chemistry: Total score = 62+62=124 So the person should study one 1 hour for chemistry and 1 hour for biology. If the person had 3 hours , he has two options: a) 2 hours chemistry and 1 hour biology: Total score= 67+62= 129 b) 2 hours biology and 1 hour chemistry: Total score= 62+66 = 128 So if the person has 3 hours , he should study 2 hours for chemistry and 1 hour for biology.
