A student took five papers in an examination, where the full marks were the same for each paper. His marks in these papers were in the proportion of 6 : 7 : 8 : 9 : 10. In all papers together, the candidate obtained 60% of the total marks. Then the number of papers in which he got more than 61% marks is	Choose the correct choice from the following answers
A) 6
B) 5
C) 4
D) 3
E) 2
Here we can assume that one subject is of 100 marks so total there are 5 subjects =&gt; 100*5= 
<gadget id="calculator">100*5</gadget>
<output>500</output>
500.   Now according to the question he secured 60 % of those which is 60%of 500= 300 marks in total.   The ratio between the marks is given as 6 : 7 : 8 : 9 : 10 , so now we can distribute 300 marks according to the ratio.   Total ratio = 40   For 6 : (300/40)*6= 
<gadget id="calculator">(300/40)*6</gadget>
<output>45</output>
45   Similarly , we will get for others as 52.5 , 60 , 62.5 , 75.   Hence , there are 2 subject where he secured more that 50 %.   The answer is 2.   2
