Some water will freeze, giving off latent heat, all of the water will absorb it to reach 0,
let total water be x gm.
y gm freezes.
That y gm will release 80y calorie of latent heat.
x gm will reach 0, taking 15x calorie.
15x = 80y
y/x = 3/16
can't think more rite now
but this isn't the correct answer
