Question
Two third part of cylinder is full of water. When we
tilt the cylinder in such a way that the water becomes diagonal shape, in this process 87.5 litre of water is flown out. Find the capacity of cylinder?Solution
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.
