Consider two different cloth – cutting processes. In the first one, n circular cloth pieces are cut from a square cloth piece of side ‘a’ in the following steps: the original square of side ‘a’ is divided into n smaller squares, not necessarily of the same size; then a circle of the maximum possible area is cut from each of the smaller squares. In the second process, only one circle of the maximum possible area is cut from the square of side ‘a’ and the process ends there. The cloth pieces remaining after cutting the circles are scrapped in both the processes. The ratio of the total area of the scrap cloth generated in the former to that in the later is: (a) 1:1 (b) 2–√:1 (c) n(4−π)4n−π (d) 4n−πn(4−π)
