Eva learns for two semesters in a year. In 2019, she scored ten more marks in maths in the first semester than the second, 15 marks less in arts, and 1/3 marks less in science in the first semester than the second. If she got 80 marks in maths in the second semester, 90 marks in arts, and 90 in science, what's the total number of her marks in all the semesters?
In the first semester, she scored 80+10 = <<80+10=90>>90 marks in maths
She also scores 90-15 = <<90-15=75>>75 marks in arts in the first semester.
She scored 1/3 marks less in science in the first semester than the second, which is 1/3*90 = <<1/3*90=30>>30
Her score in science in the first semester is 90-30 = <<90-30=60>>60
The total for the first semester is 90+75+60 = <<90+75+60=225>>225
The total for the second semester is 90+90+80 = <<90+90+80=260>>260
The combined marks for all the semesters in 260+225 = <<260+225=485>>485
