A student has got marks in five subjects in the ratio 2:3:4:5:6 .The maximum marks of subjects in same sequence are in ratio 6:5:8:4:7.Total percentage of marks scored by him is 48%.FInd the maximum percentage obtained by him in a subject..	Answers: A) 65 B) 78 C) 96 D) 90 E) 95
lets marks obtain 2x,3x,4x,5x,6x.   total marks 6y,5y,8y,4y,7y.   addition of marks obtain=(2x+3x+4x+5x+6x)=20x   addition of total marks(2 +3 +4 +5 +6 )= 
<gadget id="calculator">(2 +3 +4 +5 +6 )</gadget>
<output>20</output>
20x   addition of total marks=(6y+5y+8y+4y+7y)=30y   so percentage(6 +5 +8 +4 +7 )= 
<gadget id="calculator">(6 +5 +8 +4 +7 )</gadget>
<output>30</output>
30y   so percentage=(20x/30y)*100   (20x/30y)*100=48   so,x/y=18/25   as we observed 5x/4y is the maximum marks   so 5x/4y=5/4*18/25*100= 
<gadget id="calculator">5/4*18/25*100</gadget>
<output>90</output>
