It All Started Nice and Easy...
Then, find the sum of all roots of the equation \(2(A+2)x^4+32x^3+Ax^2-(A+37)x+49=0\). Take the reciprocal of this number to be n. Then find the first 3 significant figures of the infinite sum \(1/(2^n) +1/(2^n+1)+ 1/(2^n+2)\)... This 3 digit number is K.
Imagine you have a ball, which you throw at angle of \(30 ^\circ\) to the horizontal at speed K. Find the time taken for this ball to touch the ground again, assuming that it remains in the same gravitational field and the gravitational force on the ball does not change with distance or height. This is W.
Now imagine that you have W objects laid out in front of you. What is the number of ways to arrange them in a row, knowing that two of them are exactly identical and cannot be differentiated. The number length of this number is H.
How many squares can be drawn on a \(H \times H\) chessboard?" The man sat deep in thought for 5 minutes. Then he said: "the number of squares that can be drawn are the number of stupid problems that you have posed".
The troll leaped with glee, for the man had answered incorrectly. He had not taken into account this very problem! The man had got the answer wrong by one!
How many stupid problems has the troll posed, excluding this one? This is an entry in the Troll King Contest.
