Question
Given area four cylindrical buckets A, B, C, D whose circular bases are of radii 2, 4, 6, 8 units, respectively. Initially water is filled in these buckets up to the same height. Some water is then transferred from D to A and B so that they all three have the same volume of water. Some water is then transferred between C and B so that they both have the same volume of water. If , denote the heights of water at this stage in the buckets A, B respectively, then the ratio equals –
