a) 1
b) 3
c) 4
d) 5
Answer: c
Explanation: Let the marks obtained in five subjects be 6x, 7x, 8x, 9x and 10x.
Total marks obtained = 40x
Max. Marks of the five subjects = $$\frac{{40{\text{x}}}}{{0.6}}$$ [40x is 60% of total marks]
Max. Marks in each subject = $$\frac{{40{\text{x}}}}{{0.6 \times 5}}$$ = 13.33x
Hence, % of each subject = $$\frac{{6{\text{x}} \times 100}}{{13.33}}$$ = 45.01%
$$\frac{{7{\text{x}} \times 100}}{{13.33}}$$ = 52.51
In same way other percentage are 60.01%, 67.52%, 75.01%.
Number of subjects in which he gets more than 50% marks = 4
