Three containers A, B and C are filled with water at different temperature. When 1 litre of water from A is mixed with 2 litre of water from B, the resulting temperature of mixture is $$52^\circ\text{C}$$. When 1 litre of water from B is mixed with 2 litre of water from C, the resulting temperature of mixture is $$40^\circ\text{C}$$. Similarly when 1 litre of water from C is mixed with 2 litre of water from A, the resulting temperature of mixture is $$34^\circ\text{C}$$. Temperature of mixture when one litre of water from each container is mixed (neglect the water equivalent of container) is
