Question

Total marks obtained by a student in physics, chemistry and maths together is 120 more than the marks obtained by him in chemistry.what are the average marks obtained by him in physics and maths together​

Answer 1

Answer:

60

Step-by-step explanation:

ACCORDING TO GIVEN CONDITION

SUM OF MARKS IN THREE SUBJECT(P,C,M)

P+C+M=120+C

P+C+M-C=120-C+C

P+C=120

AVERAGE MARKS OF P&C = 120/2=60

HENCE 60 IS YOUR ANSWER

Answer 2

Step-by-step explanation:

Given that

Total marks in physics(P) chemistry(C) and math(M) together is 120 more than chemistry

To find avg marks obtained in physics and math together.

Solution

As per given condition

$p + c + m = 120 + c$

Substracting C from both side we get

$p + m = 120$

hence average will be

$average \: = \frac{120}{2} \\ = 60$

hence average marks obtained in physics and math together is 60.
