Let Joseph scored X marks .
Marks scored by Amit in examination = ( X - 10 ) marks.
Marks scored by Anil in examination = ( X + 15 ) marks.
Given :-
X + X - 10 + X + 15 = 245
3X + 5 = 245
3X = 245-5
3X = 240
X = 240/3
X = 80
Marks scored by Joseph = X = 80 marks
Marks scored by Amit = X - 10 = 80-10 = 70 marks.
Marks scored by Anil = X + 15 = 80+15 = 95 marks.
Marks scored by Amit in examination = ( X - 10 ) marks.
Marks scored by Anil in examination = ( X + 15 ) marks.
Given :-
X + X - 10 + X + 15 = 245
3X + 5 = 245
3X = 245-5
3X = 240
X = 240/3
X = 80
Marks scored by Joseph = X = 80 marks
Marks scored by Amit = X - 10 = 80-10 = 70 marks.
Marks scored by Anil = X + 15 = 80+15 = 95 marks.
