A thermally insulated pot has 200 g ice ...

A thermally insulated pot has 200 g ice at temperature ` 0^(@)C`. How much steam of ` 100^(@)C` has to be mixed to it, so that water of temperature ` 40^(@)C` will be obtained?
(Given: Latent heat of melting of ice = 80 cal/g,
latent heat of vaporisation of water = 540 cal/g,
specific heat of water `= I " cal/g " ^(@)C) `
