Correct Answer: One
Solution :
Let the maximum mark be 100.
So, for all three maximum marks will be = 100 × 3 = 300.
The sum of the scores obtained by Ram and his two friends in an exam is 60% of the sum of the maximum marks = 60% of 300 = 60 ÷100 × 300 = 180
Now, the ratio of their obtained marks is 4: 5: 6
4x + 5x + 6x = 180
15x = 180
x = 180 ÷ 15
x = 12
The marks obtained by the persons = 4x, 5x and 6x;
48, 60, and 72.
So, only one person scored more than 70% marks. Hence, the third option is correct.
