MAXIMUM MARKS:
M:E:S = 3X:2X:5X
Now, 3x+2x+5x=500; x= 50
Therefore maximum marks that can be obtd in,
M:E:S = 150: 100:250
Now OBTAINED MARKS:
M:E:S (in percentage) = 50:68:?
Overall marks obtained is 73(in percentage)
That is, (73/100)*500 = 365
Similarly for M = (75/100)*150 = 112.5
For E = (68/100)*100 = 68
Remaining marks is for S = 365 - (112.5 + 68)= 365 - 180.5
= 184.5
In % = 73.8%

Samuel is obviously a bad fisherman. During the past season, in which he and the five members of his team spent four months on a boat together off Dutch Harbor, AK, he caught fewer fish than any of his teammates. Which of the following, if true, most weakens the argument above? While fishing this past season, Samuel fell sick for a week and did not catch any fish during this time. Before becoming a fisherman, Samuel piloted a fishing boat whose members regularly caught record numbers of fish. Unlike the other fishermen on his boat, at the order of the captain, Samuel fished this past season with experimental bait. Two seasons ago, Samuel fished on another boat off Dutch Harbor and caught more fish than any other member of that boat.
