Energy to heat up the Ice is equal to the energy taken from the boiling water.
deltaE_ice = (m_ice*c*deltaT_ice)+m_ice*l (where c is specific heat and l is latent heat)
deltaE_water = m_water*c*deltaT_water
Then the boiling water is initially at 100 degC and melting ice is at 0 degC so:
100+deltaT_water = deltaT_ice (where deltaT_water < 0)
You know have two equations and two unknowns....so you know what to do.
Disclaimer- I am not rigorous with signs, I'm sure you'll work it out from what I put though.
