Physics Homework Help-Specific Heat and Heat of Fusion?

This is the exact question: While casting a silver ornament, a silversmith pours 0.12 kg of molten silver at 1010 degrees celsius into a 2.40 kg iron mold at a temperature of 35 degrees celsius. What will be the equilibrium temperature of the silver casting and mold? Assume no thermal energy is lost to the surrounding environment.

Information:
Heat of Fusion (Iron)= 2.66*10^5 J/kg
Melting Point (Iron)= 1535 C
Specific Heat (Iron as a solid)= 450 J/kg*C
Heat of Fusion (Silver)= 1.04*10^5 J/kg
Specific Heat (Silver as a solid)= 235 J/kg*C
Specific Heat (Silver as a liquid)= 290 J/kg*C
Melting Point (Silver)= 960 C

I seem to think that I have been given too much information and that this is a trick question. I could be mistaken though.

Thanks
