To come to a common temperature, First of all the ice will come to 0 degrees

heat=m*s*change in temp=2000 joules

then the ice will melt

heat=m*latent heat of fusion= 1670 joules

therefore now water at 0 degrees will gain heat and water at 30 degrees will lose heat. and according to the conservation of heat we can calculate the common temperature.

$2000+1670+.005\times s_{water}\times \Delta T_{1}=.019\times s_{water}\times \Delta T_{2}$

Thanks and Regards

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
