Step-by-step explanation:
Let the marks obtain in English be x then marks obtain in mathematics will be x + 7
then marks obtain in physics will be x + 7 + 5
A/Q = x +(x+7)+(x+7+5) = 265
= 3x + 19 = 265
= 3x = 246
= x = 246/3 = 82
marks obtain in English = 82
marks obtain in mathematics = x +7= 82+7= 89
marks obtain in physics = x +7+5= 94
