A thermometer of mass 55 g and specific heat `"0.2 cal.g"^(-1).^(@)C^(-1)` reads `15^(@)C` at the room temperature. When the thermometer, it reads `44.4^(@)C`. If the water equivalent of the calorimeter is 50 g and the mass of water taken is 250 g, find the temperature of water before the immersion of the thermometer.
