Question

The total marks obtained by a student in Physics, Chemistry and Mathematics together is 120 more than the marks obtained by him in Chemistry. What are the average marks obtained by him in Physics and Mathematics together?

• A. 60
• B. 120
• C. 40
• D. Cannot be determined
• E. None of these

Answer 1

The correct option is A 60

Let the marks obtained in Physics, Chemistry and Mathematics be P, C and M respectively
According to given,
P + C + M = C + 120
$\therefore$ P + M = 120
$\frac{P+M}{2}=60$
