Question of the day
A man stands in the center of a circle. On the circumference of the circle is a tiger that is constrained to move only around the circle. The tiger can run four times as fast as the man. How can the man escape the circle without being eaten by the tiger? (The tiger will try to minimize its distance from the man at all times)...

Question of the day - Expert Math club problem
The Expert Math club took a field trip to see the movie MATH IS FUN.
A total of 27 people went on the trip, including students, teachers, and some parents.
There were more parents than teachers.
Movie tickets cost $7, but the students got a discount and only had to pay $3 each.
The group paid a total of $105.
How many students, teachers, and parents went on the trip?

How many rectangles are there in an mxn grid?
Let us consider the
following grid with m rows and n columns:
Number of rectangles
with dimension 1X1 = m*n
Number of rectangles
with dimension 2X1 = (m-1)*n
Number of rectangles
with dimension 3X1 = (m-2)*n
....................
Number of rectangles
with dimension mX1 = [(m-(m-1)]*n
Similarly,
Number of rectangles
with dimension 1X2 = m*(n-1)
Number of rectangles
with dimension 2X2 = (m-1)*(n-1)
Number of rectangles
with dimension 3X2 = (m-2)*(n-1)
..............
Number of rectangles
with dimension mX2 = [(m-(m-1)]*(n-1)
Increasing the number
of columns incrementally by 1, the last set of number of rectangles with n
columns are
Number of rectangles
with dimension 1Xn = m*1
Number of rectangles
with dimension 2Xn = (m-1)*1
Number of rectangles
with dimension 3Xn = (m-2)*1
.....................
Number of rectangles
with dimension mXn = [(m-(m-1)]*1
Sum (1X1, 2X1,
3X1…..mX1) = n * [m + (m-1) + (m-2)
+……1]
= n * m(m+1)/2
Sum (1X2, 2X2,
3X2…..mX2) = (n-1) * [m + (m-1) + (m-2) +……1]
= (n-1) * m(m+1)/2
Sum (1X3, 2X3,
3X3…..mX3) = (n-2) * [m + (m-1) + (m-2) +……1]
= (n-2) * m(m+1)/2
.....................
Sum (1Xn, 2Xn,
3Xn…..mXn) = [(n-(n-1)] * [m + (m-1) + (m-2) +……1] = 1 * m(m+1)/2
And total number of
rectangles will be sum of the sums of rectangles of various sizes
So, S = [m(m+1)/2] *
[n + (n-1) + (n-2) +…….1]
S = [m(m+1)/2] * S =
[n(n+1)/2]
S = mn(m+1)(n+1)/4
