A student appeared in 3 papers of Maths, English and
Science. The maximum marks of the three papers are in the
ratio of 3 : 2 : 5 and total of 3 papers is 500. He obtained
50% in Maths, 68% in English ,and 73% overall.
What is the percentage marks he scored in Science?
Answer Posted / ds
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%

Q1. Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line, .i.e the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The minimum value of n1(P) over all configurations P of 5 points in the plane in general position(.i.e no three points in P lie on a line) is
