The following ternary figure shows the marks obtained by students A, B and C in an exam of 100 marks. Here, C received 10 marks in Physics, 50 marks in Chemistry and 40 marks in Mathematics.

Which one of the following is CORRECT?

Correct option is B

Solution: From the ternary diagram:
· For C, the given values are:
· Physics = 10
· Chemistry = 50
· Mathematics = 40 (This matches point C on the diagram.)
Now analyze A and B from their positions.
Student A: · Mathematics ≈ 80
· Physics ≈ 10
· Chemistry ≈ 10
So:
· A’s Chemistry marks = 10
· A has not scored 20 or 80 in Chemistry
Thus:
· Option (c) is false
· Option (d) is false
Student B: · Mathematics ≈ 40
· Physics ≈ 40
· Chemistry ≈ 20
So:
· B has scored equal marks in Mathematics and Physics
Check remaining options: (a) A’s Chemistry (10) > C’s Physics (10) → false (b) B has scored equal in Mathematics and Physics → true
Correct answer: (b)
