How many grams of a liquid of specific heat 0.2 at a temperature 40^(@)C must be mixedwith 100 gm of a liquid of specific heat of 0.5 at a temperature 20^(@)C , so that the final temperature of the mixture becomes 32^(@)C

What mass of a liquid A of specific heat capacity 0.84 J g^(-1) K^(-1) at a temperature 40^@ C must be mixed with 100 g of a liquid B of specific heat capacity 2.1 J g^(-1) K^(-1) at 20^@ C, so that the final temperature of mixture becomes 32^@ C ?

A liquid of specific heat 0.5 cal/ g^(0) c at 60^(0) C, is mixed with another liquid of specific heat 0.3 cal/ gm^(0) c at 20^(0) C. After mixing, the temperature of the mixture becomes 30^(0) C. In what proportion by weight are the liquids mixed ?

A liquid A of specific heat 0.5 at 60^(@)C is mixed with another liquid B of specific heat 0.3 at 20^(@)C . After mixing, the resultant temperature of the mixture is 30^(@)C . The ratio of masses of A and B respectively is
