The total marks obtained by a student in three subjects A, B and C together is 80 more than the marks obtained by B. What the average marks obtained by A and C together?
Explanation
The total marks obtained in 3 subjects A, B, C is 80
= 3×80= 240
The marks obtained by B is more than A and C
B= 40, A= 20, C= 20
The marks obtained by A and C together = A+C
= 20+20
= 40
Hence, Option C is correct.
