When a hot liquid is mixed with a cold liquid, the temperature of the mixture

Temperature of two liquids are 80^(@)C and 20^(@)C . When they are mixed in the mass ratio of 8:5 , the temperature of the mixture becomes 60^(@)C . Find the ratio of their specific heats.

A, B and C are three liquids. 4 g of liquids A at 60^(@)C is mixed with 1 g of liquid C at 50^(@)C , the final temperature of the mixture is 55^(@)C . Again, if 1 g of liquid A (at 60^(@)C ) is mixed with 1 g of liquid B at 50^(@)C , the final temperature of the mixture becomes 55^(@)C . What will be the final temperature if 1 g of liquid B at 60^(@)C is mixed with 1 g of liquid C at 50^(@)C ?

A liquid of mass m and specific heat c is heated to a temperature 2T. Another liquid of mass m/2 and specific heat 2 c is heated to a temperature T. If these two liquids are mixed, the resulting temperature of the mixture is
