Let the volume of the cylinder be X. Water in cylinder = (2/3)X When we tilt the cylinder, the water becomes the diagonal shape i.e half of water left and 87.5 litres of water flown out. => (2/3)X - 87.5 = X/2 => 2X - 262.5 = (3/2)X => -262.5 = -(X/2) => X = 525 litre Therefore, The capacity of the cylinder is 525 litre.
