Here, you will find all the questions of ISI Entrance Paper 2010 from Indian Statistical Institute's B. Math Entrance. You will also get the solutions soon of all the previous year problems.
Problem 1:
Prove that in each year, the th day of some month occurs on a Friday.
Problem 2:
In the accompanying figure, is the graph of a one-to-one continuous function
. At each point
on the graph of
, assume that the areas
and
are equal. Here
are the horizontal and vertical segments. Determine the function
.
Problem 3:
Show that. for any positive integer the sum of
consecutive positive integers cannot be a perfect square.
Problem 4:
If satisfy
prove that
.
Problem 5:
Let be positive real numbers. Compute
.
Problem 6:
Let each of the vertices of a regular -gon (polygon of
equal sides and equal angles) be coloured black or white.
(a) Show that there are two adjacent vertices of the same colour.
(b) Show there are 3 vertices of the same colour forming an isosceles triangle.
Problem 7:
Let be real numbers and. assume that all the roots of
