Consider a rectangular grid of lines formed by m parallel lines intersecting n parallel lines that running perpendicular to them. How many different paths along the grid are possible from the top right corner to the bottom left corner? (where only downward and leftward motion is allowed)
An operation is defined as cutting the maximum possible circle from a square and then cutting the maximum possible square from that circle. If the area of the square with which the operations started is 64 sq.units, what will be the area of the figure that will be formed after exactly 2.5 operations (half operation is defined as cutting the maximum possible circle from the square)?
