JEE Advanced 2019 Paper 1

A liquid at 30ºC is poured very slowly into a Calorimeter that is at temperature of 110ºC. The boiling temperature of the liquid is 80ºC. It is found that the first 5gm of the liquid completely evaporates. After pouring another 80gm of the liquid the equilibrium temperature is found to be 50ºC. The ratio of the Latent heat of the liquid to its specific heat will be ___ºC.
