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 $52^{{}^{{}^{\circ}}} \mathrm{C}$. When 1 litre of water from B is mixed with 2 litre of water from C , the resulting temperature of mixture is $40^{{}^{{}^{\circ}}} \mathrm{C}$. Similarly when 1 litre of water from C is mixed with 2 litre of water from A , the resulting temperature of mixture is $34^0 \mathrm{C}$. Temperature of mixture when one litre of water from each container is mixed (neglect the water equivalent of container) is
