Answer:
marks in science = 85
marks in english = 35
Explanation:
average marks in science and maths = 70
marks in maths = 55
let marks in science = x
x + 55 / 2 = 70
x + 55 = 140
x = 140 - 55 = 85
thus marks obtained in science, x = 85
average marks in science and english = 60
let marks in english = y
85 + y / 2 = 60
85 + y = 120
y = 120 - 85 = 35
thus marks obtained in english, y = 35
